One clarification...

4.2/4.3 and "use W3C or other standard technologies" are related, but not 
identical.  It would be possible to make the framework available on all 
platforms without using standard technologies.


>11) This is exactly the reason for the Ck 2.3, 2.4. I call them "sample

...and maybe terminology -- 2.3/2.4 don't say "sample tests', but rather 
"sample test scenarios", which is not very suggestive.  Furthermore, 2.3 
starts off "Before creating test cases for...," and ""Those are not actual 
tests..."  The SVG Basic Effectivity TS -- a functionally comprehensive 
sample test suite of 125 actual tests -- was a useful deliverable in its 
own right.  Its 125 test cases were "samples" in the sense that 
collectively they comprised a uniform (but somewhat sparse) sampling of the 
entire functional breadth of SVG.

Long story short, I'm still a bit little uncertain whether we're talking 
about the same thing.  But I'll take your word for it and look out for the 
next revision.
