Notes and Potential Issues

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.

  1. Warning DOCTYPE Override in effect!

    The DOCTYPE Declaration for "SVG 1.1" has been inserted at the start of the document, but even if no errors are shown below the document will not be Valid until you add the new DOCTYPE Declaration.

Congratulations

The document located at <https://upload.wikimedia.org/wikipedia/commons/d/dc/Endosymbiosis.svg> was tentatively checked as SVG 1.1. This means that with the use of some fallback or override mechanism, we successfully performed a formal validation of it. In other words, the document would validate as SVG 1.1 if you changed the markup to match the changes we have performed automatically, but it will not be valid until you make these changes. The parser implementations we used for this check are based on OpenSP (SGML/XML) and libxml2 (XML).
