That time was indeed "wasted" if there was One True Issues-tracking
Scheme that was perfect for everybody. Or, at least, if all such
perfect schemes had already been invented. On all other cases, the
time was not wasted, but spent, possibly doing useful work.

I believe we are in agreement here. Working groups would clearly
benefit from a well-documented and supported set of markup languages
to write their specs. If currently available languages are not
sufficient, and if W3C members allocate resources for writing new
"markup for writing standards" languages, nobody should object to
writing those languages.

My only recommendation is that W3C does not _mandate_ a complex
one-size-fits-all language based on current requirements. As you said,
W3C can and should mandate high-level "quality" properties (where such
properties can be identified and formulated in a non-discriminatory
way).

Uniformity will help QAWG. Diversity will hurt QAWG. QAWG work is very
important but nevertheless _secondary_ to the work of other groups.
Other working groups invent and produce; QAWG just helps them along,
on a meta-level. QAWG can help by offering a "QA Collection". QAWG
should not restrict WG group choice to that Collection or to a
specific item in that Collection.

In other words, QAWG should tell other WGs:

	"If you use our tools/formats, here are the benefits and
	drawbacks you get. If you do not use our tools/formats,
	you are on your own, but let us know if your custom
	tools/formats should be added to QA Collection. Whatever
	you use, here are the meta-level rules you must obey."

Re-invention is bad. Re-invention can be reduced by documenting and
supporting already invented. Re-invention is better than prohibition
on invention (no-invention).
