Thread-Topic: Entire XML in memory?

In v1, the document exists entirely in memory.  In v2, I am making the
xml store backend pluggable so that one may provide alternate backends
with different characteristics.  In addition to a high performance,
in-memory store (the default), I will make a memory mapped backend which
stores the XML in a memory mapped file and does not consume VM memory
proportional to the size of the XML being worked on which will allow one
to load very large documents.  I can imagine backends which
incrementally load parts of a document.

This architecture is very much incomplete and in flux.  Unless you want
to be chasing my changes, I would give it a few months.

I'm interested in the answer to this one as well, though I think the
answer
is no, the whole doc is not in memory.  It may have different answers
depending on how one navigates the instance, however.

My interest is using XMLBeans in a J2ME PersonalProfile application.
I've
just started this today, and my initial impression is that v2's design
goals
are more in line with what I need to do.  Without reading the entire
list,
can I get a feel for how far along v2 is?
