Validation Output: 400 Errors

  1. Error Line 57, Column 18: there is no attribute "language"
    <script language="JavaScript">var s_account="aoldeveloper,aolsvc"</script>

    You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).

    This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.

    How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute. If you received this error when using the <embed> element to incorporate flash media in a Web page, see the FAQ item on valid flash.

  2. Error Line 57, Column 30: required attribute "type" not specified
    <script language="JavaScript">var s_account="aoldeveloper,aolsvc"</script>

    The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.

    Typical values for type are type="text/css" for <style> and type="text/javascript" for <script>.

  3. Error Line 58, Column 68: required attribute "type" not specified
    <script language="JavaScript" src="http://o.aolcdn.com/omniunih.js"></script>

    The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.

    Typical values for type are type="text/css" for <style> and type="text/javascript" for <script>.

  4. Error Line 60, Column 30: required attribute "type" not specified
    <script language="JavaScript">// <![CDATA[

    The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.

  5. Warning Line 90, Column 93: cannot generate system identifier for general entity "siteState"
    …ogin/login.psp?sitedomain=dev.aol.com&siteState=OrigUrl%3Dhttp%253A%252F%252Fd…

    An entity reference was found in the document, but there is no reference by that name defined. Often this is caused by misspelling the reference name, unencoded ampersands, or by leaving off the trailing semicolon (;). The most common cause of this error is unencoded ampersands in URLs as described by the WDG in "Ampersands in URLs".

    Entity references start with an ampersand (&) and end with a semicolon (;). If you want to use a literal ampersand in your document you must encode it as "&amp;" (even inside URLs!). Be careful to end entity references with a semicolon or your entity reference may get interpreted in connection with the following text. Also keep in mind that named entity references are case-sensitive; &Aelig; and &aelig; are different characters.

    If this error appears in some markup generated by PHP's session handling code, this article has explanations and solutions to your problem.

    Note that in most documents, errors related to entity references will trigger up to 5 separate messages from the Validator. Usually these will all disappear when the original problem is fixed.

  6. Error Line 90, Column 93: general entity "siteState" not defined and no default entity
    …ogin/login.psp?sitedomain=dev.aol.com&siteState=OrigUrl%3Dhttp%253A%252F%252Fd…

    This is usually a cascading error caused by a an undefined entity reference or use of an unencoded ampersand (&) in an URL or body text. See the previous message for further details.

  7. Warning Line 90, Column 102: reference not terminated by REFC delimiter
    …n.psp?sitedomain=dev.aol.com&siteState=OrigUrl%3Dhttp%253A%252F%252Fdev.aol.co…

    If you meant to include an entity that starts with "&", then you should terminate it with ";". Another reason for this error message is that you inadvertently created an entity by failing to escape an "&" character just before this text.

  8. Warning Line 90, Column 102: reference to external entity in attribute value
    …n.psp?sitedomain=dev.aol.com&siteState=OrigUrl%3Dhttp%253A%252F%252Fdev.aol.co…

    This is generally the sign of an ampersand that was not properly escaped for inclusion in an attribute, in a href for example. You will need to escape all instances of '&' into '&amp;'.

  9. Error Line 90, Column 102: reference to entity "siteState" for which no system identifier could be generated
    …n.psp?sitedomain=dev.aol.com&siteState=OrigUrl%3Dhttp%253A%252F%252Fdev.aol.co…

    This is usually a cascading error caused by a an undefined entity reference or use of an unencoded ampersand (&) in an URL or body text. See the previous message for further details.

    …n.psp?sitedomain=dev.aol.com&siteState=OrigUrl=http%3A//dev.aol.com/&createSn=…

    If you meant to include an entity that starts with "&", then you should terminate it with ";". Another reason for this error message is that you inadvertently created an entity by failing to escape an "&" character just before this text.

  12. Warning Line 91, Column 93: reference to external entity in attribute value
    …n.psp?sitedomain=dev.aol.com&siteState=OrigUrl=http%3A//dev.aol.com/&createSn=…

  25. Warning Line 139, Column 34: character "&" is the first character of a delimiter but occurred as data
    	<li><a href="#draganddrop">Drag & Drop</a></li>

    This message may appear in several cases:

    • You tried to include the "<" character in your page: you should escape it as "&lt;"
    • You used an unescaped ampersand "&": this may be valid in some contexts, but it is recommended to use "&amp;", which is always safe.
    • Another possibility is that you forgot to close quotes in a previous tag.
  26. Error Line 162, Column 4: document type does not allow element "li" here; missing one of "ul", "ol" start-tag
    <li><a href="#global">Global Recommendations</a></li>

    The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.

    One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").

    … important information (<a href=http://www.w3.org/WAI/PF/aria/#alert>ARIA Aler…

    This error may occur when there is a mistake in how a self-closing tag is closed, e.g '.../ >'. The proper syntax is '... />' (note the position of the space).

  42. Error Line 185, Column 106: end tag for element "a" which is not open
    …tant information (<a href=http://www.w3.org/WAI/PF/aria/#alert>ARIA Alert</a>).

    The Validator found an end tag for the above element, but that element is not currently open. This is often caused by a leftover end tag from an element that was removed during editing, or by an implicitly closed element (if you have an error related to an element being used where it is not allowed, this is almost certainly the case). In the latter case this error will disappear as soon as you fix the original problem.

    If this error occurred in a script section of your document, you should probably read this FAQ entry.

    <li><h2><a name="dialogtooltip">Dialog (Tooltip)</a></h2></li>

    The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed).

    One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error).

This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.

For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error).

    One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error).

    The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed).

    One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error).

    The Validator found an end tag for the above element, but that element is not currently open.

In the latter case this error will disappear as soon as you fix the original problem.

    You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).

    This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.

    How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute.
