Certainly!  The things I'd change would involve substantial
modifications that probably aren't worth making for most users.

Yep.  I'd like to see some place for these to find a home, and maybe
accrete into a library.  I'm aware of implementation of several of the
pieces I listed in particular projects, though they aren't available
separately or as open source.  

Basically, I'd like to see more freely available tinkertoys for use with
SAX.  That can happen over time as various authors contribute or
instantly if someone gets the urge to write and publish these bits.

That sounds more useful to me.  Is the only required change [extends
XMLPipelineImpl] instead of [extends XMLFilterImpl]?
