locality is a bit of a problem since you don't want tex's grouping to
interfere;
this is why the following method is to be used (eg):
\defineXMLenvironment[whatever][bla=,junk=]
now, each time the element is encountered, 'bla' and 'junk' are set to
nothing, so you start afresh.
concerning the second question: there is \XMLpar{element}{name}{default}
and there will be a \XMLparself too as well as a \XMLNSpar one for
namespaced pars (this kind of works now). There are (in the release that
will be posted soon) now severel modes of operandi with respect to handling
element namespaces and attribute namespaces. I just implemented &#number;
things and there are methods to turn thngs like
key="value&value;and&tex;and{andworseé"
into tex robust things (again several methods) which is handy when they are
used in for instance cross referencing.
[as a bonus the module is sped up a bit; i use the maps biblography as
reference run: some 139 sec now, while 150 last month).
