That is very good news.

I would very much encourage you to do that. What specific aspect of the
XML syntax currently requires hand editing on your part?

So are many of the other implementations tested.

The test suite has two parts - the test files themselves (svg files) and
the test suite harness (html files, svg files, png images, and so
forth). They have different licenses.

You are allowed to modiify the harness or use your own, or load the
files oneby one from a file browser, or instrument your viewer to
iterate through them all, or whatever you wish.

You are not allowed to alter the actual svg tests themselves in any way.
Well, you can, but they are no longer the W3C test suite and you can't
claim anything regarding them.

However, running the html harness (possibly on a different computer or
different screen) at the same time is helpful because
you can see the reference png and read the instructions.

JL>   * How would I go about making a submission?

I will send you an xml file to fill in. I would also need to see the
tests running in the implementation to verify that the tests are passed
