[JDEV] *Real* element.h usage doc

I was going to do that(merge CDATA together during parsing)... actually, I
don't know why I didn't, lazy I guess :)

That should be easy stuff... take a look at the xpt Expat handlers, yours
will be almost identical.  The only funky thing I'm doing is the two-teir
parsing via xptpool, where you are "packetizing" the branch of tags under
the root tag.  Let me know if you have any ?s, I'll be busy on other
things for a while yet, but will be happy to help after 0.6...

After the last batch of checkins I just did, the only major stuff I have
to really look at seriously and hook up are status-related issues.  Then
I'll be updating the little CLI test client and go into major testing
mode.
