DOM-like classes (was Re: Xalan 2.0: the plan)

Hey Pier, you could easily contribute these classes today for Xalan 1.0.1.

What I need for the SAX input driver mode is a cross between the DTM and a
DOM, incremental, with read-only interface, supporting just a subset of the
DOM interfaces (for instance, I don't need getChildren), and holding a
document-order index.  These could be integrated in in less than a day (if
they can be easily built with SAX2), if they are reasonably robust, with a
massive performance improvement for the SAX input configuration (and Cocoon
2).  If you don't string-ize character data and let me set and get at the
sax character array, it will be even faster.

If Pier isn't willing, if anyone else wants to take this on, let me know.
I think this is probably only a day or two of work.

It depends if I (we, there are a bunch of people working on that) can
MAKE it for the 1.0.1.

Good points.... We're not string-ing characters right now, we're
preserving everything as comes from the SAX2 interfaces... We'd have to
post those classes one of these days...

I don't have two days right now :( But I believe it's necessary to come
up with a simpler, lighter and easier document object model (built
incrementally, and so on, like the DTM is) :)
