The following notes and warnings highlight missing or conflicting information which caused the validator to perform some guesswork prior to validation, or other things affecting the output below. If the guess or fallback is incorrect, it could make validation results entirely incoherent. It is highly recommended to check these potential issues, and, if necessary, fix them and re-validate the document.
Mismatch between Public and System identifiers in the DOCTYPE declaration
This document uses an inconsistent DOCTYPE declaration.
The Public Identifier
-//W3C//DTD SVG 1.0//EN declares the
SVG 1.0 document type, but the associated System Identifier
http://www.w3.org/Graphics/SVG/1.0/DTD/svg10.dtd does not match this document type.
The recommended System Identifier
for SVG 1.0 is http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd.
The safest way to use a correct DOCTYPE declaration is to copy and paste one from the recommended list and avoid editing that part of your markup by hand.
The document located at <https://upload.wikimedia.org/wikipedia/commons/4/4a/Pictogram_voting_info.svg> was successfully checked as SVG 1.0. This means that the resource in question identified itself as "SVG 1.0" and that we successfully performed a formal validation of it. The parser implementations we used for this check are based on OpenSP (SGML/XML) and libxml2 (XML).
To show your readers that you have taken the care to create an interoperable Web page, you may display this icon on any page that validates. Here is the HTML you could use to add this icon to your Web page:
<p>
<a href="https://validator.w3.org/markup/check?uri=referer"><img
src="https://www.w3.org/Icons/valid-svg10" alt="Valid SVG 1.0" height="31" width="88" /></a>
</p>
A full list of icons, with links to alternate formats and colors, is available: If you like, you can download a copy of the icons to keep in your local web directory, and change the HTML fragment above to reference your local image rather than the one on this server. See also our help items related to documents transferred over secure protocols for these icons and the "uri=referer" feature.
If you would like to create a link to this page (i.e., this validation result) to make it easier to revalidate this page in the future or to allow others to validate your page, the URI is <https://validator.w3.org/markup/check?uri=https%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2F4%2F4a%2FPictogram_voting_info.svg;ss=1> (or you can just add the current page to your bookmarks or hotlist).
If you use CSS in your document, you can check it using the W3C CSS Validation Service.
