The test suite build code already handles format conversion between XHTML and HTML, I was planning on adding support for HTML to SVG as well. I think it would be best for this to be handled as part of the build where practical.

Tav, can you send me the code you used for the conversion? I'm working on the build code next week and would be happy to integrate it.

TAV: Done. Code was written specifically for Adobe's CSS3 transform tests and may not work generically.

Just getting the tests in the repository at https://hg.csswg.org/test with the proper metadata present should be sufficient.

One of the features I'll be adding to the build code is to allow multiple source formats for the same test where needed (it already produces multiple output formats).

This raises an interesting question. Currently when an implementation passes a test in any format available, it's considered passing (even if it fails in another format).

Do we need to track pass/fails for stand-alone SVG tests separately from the same test as SVG in HTML?

TAV: Yes, I think. Otherwise problems with stand-alone SVG will be overlooked. At the moment, I think none(?) of the major browsers handle CSS3 transforms in stand-alone SVG but then do with SVG embedded in HTML.
