This is basically the same issue that I raised last weekend, so maybe
I'm missing something.  Currently, I just work around it by unsetting
ANT_HOME before building ant. In the end, it all comes down what
should the build files do, and what assumptions should they make. 

What is the role of jakarta-ant/bootstrap.[bat|sh]?

My assumption is it's role is to build "enough ant to get
build.[bat|sh] to be able to use ant to build ant".

What is the role jakarta-ant/build.[bat|sh]?

I'm assuming it's role is to build ant using the recently bootstraped

What is the role of anything-else/build.[bat|sh]?

I'm assuming they should build their respective projects, and that
they should set up some project specific environment/options and
invoke ant.  I'm not sure why they don't use $ANT_HOME/bin/ant to do

What's the role of $ANT_HOME/bin/ant?

I thought it was to run ant, but I may be alone on this.

Where/how should people deploy JAXP, Xerces, or whatever parser they

Personally, I think that's outside of the scope of ant, though there's
no reason to make it more difficult for people than it has to be.  Ant 
(and the rest of jakarta) probably shouldn't distribute them, nor
assume they are deployed inside them. I happen to put them in my
