Hi!
As you may know, many Commoners make it a point to make SVG images
pass the W3C Markup Validation
Service, and even created a template to mark images that
don't. This system has scalability and maintainability issues, so I
have designed an apposite extension for the MediaWiki software which
I think will help automating the process for the sake of the whole
community.
You can find some technical details on
the Wikitech mailing list.
Any help to set up a request for comment on Commons will be
appreciated, thank you.
