Re: Warning about self-closing syntax in embedded SVG within HTML file

Michael – thank you. I will check it out.

MathML – I hadn’t thought of that.

The specific docs I was validating are a specification and a best practice guide for a standard called ONIX that is used in the publishing and bookselling industry, and in an effort to make each doc self-contained, the CSS, font data, JS and SVG diagrams are all embedded directly within the HTML file rather than linked via src attributes (or similar). They are both huge docs – at least, huge compared to typical web pages (4MB). One day, I’ll turn them into EPUB files…

Regards
Graham

The validators (old and nu) now provide a warning against the use of the self-closing syntax. This is fine for void elements like <br> or <meta>.

But should it also warn against self-closing syntax within SVG that is directly embedded within the HTML (not a separate SVG file linked using <img>)?

This snippet generates warnings. Is this expected behaviour? It is not the same as recommending the removal of a / from an HTML void element.
...
<path d="M 5 35 l 60 -25 10 5 5 10" />
<path d="M 75 55 l 60 -25 10 5 5 10" />

This should be fixed now — the checker should not longer be warning about
SVG or MathML elements that use self-closing-tag syntax.

Thanks again for catching this and reporting. If you find that the checker
is still doing anything unexpected, please let me know.

 –Mike
