Let me just say, that I would had no problem on considering making changes or 
adding features to the descriptors, either from the begining or over time.
But sadly, some in the committers team just plainly used the veto power
and that was the end of that.

There has been at least a million discussions on this issue. But every time 
someone comes with a patch or proposal for ANT1.x it gets vetoed because
of one comitters view or another. It is very frustraiting to get any of the major
issues addressed with this sort of reaction all the time.

This looks a litle like <roles/> from myrmidom. Which we have also discuss
in the past but to no avail with respect to ANT1.x.

Why is such a reluctance to move on ANT1.x? Are the committers afraid the if ANT1.x 
gets fixed, then ANT2 will have no reason to exist?
