Yep, it is.  All I've done is look over the proposals, and distill out the
simplest common elements, so that we can push them into the ant 1.5 tree.
I'm not proposing anything that hasn't been proposed (a thousand times)

Absolutely.  The next step after deciding on a starting point for the
descriptor format, is to extract out a task that can import type defs from
an antlib.  Jose Alberto's proposal is the only one with a task that we can
push into ant 1.5, so we'd probably start with that.

I think we want to tackle this a piece-at-a-time.  All of the proposals
include features that are experimental.  We don't want to include the
experimental bits in the ant 1.5 tree.  This is why I want to break the
process up into small steps, each with limited scope.  At the end of each
step, we end up with something in the ant 1.5 tree.  Maybe it's an entire
proposal, maybe it's a chunk of one, maybe it's a distillation of all 3,
maybe none of the above.

Good idea.  How about we just ignore stuff we don't understand?
