I'll have to think about some things more than I have time for right now.

In response to Greg's comments, I'm starting to think that namespace
processing should be a mode: either completely on or completely off. The
complex, scoped namespaces mechanism is more the result of politics than
technology -- this wasn't how namespaces were supposed to turn out.

Actually, it gets a fair amount of use and is easy to implement. DSSSL,
XSL and the grove paradigm all provide this feature. Consider:
<TITLE>This is the <CODE>XSL</CODE> introduction.</TITLE>
Now I'm generating a TOC, index or cross-reference. I don't care abou the
CODE element -- I just want to treat it as if the tags doen't exist.
I could go either way on this function, though.

That's a different feature that is also useful.

I'm surprised that you've never needed it. In Greg's data-ish world it
would be incredibly useful but also in the data-ish subsets of the
doc.documentElement.getChild( "METADATA" ).getChild( "AUTHOR" )
You can emulate this with getElementsByTagName but you incur the overhead
of building and discarding the node list.

I've never needed this one, but Greg seems to...we'll let him defend it
(here or in qp_api) when he gets back.

Simon said. "It will react to its surroundings and will talk."
