Okay.  Do we really need UniversalName as a *class*, or is it sufficient
(as I continue to believe) to represent it as a String, possibly
interned?  If the latter, then my ParserFilter approach will work
fine, returning all element names in the universal form of
URI + delimiter + localPart (where URI can be null), and all
attribute names in the form URI + delimiter + localPart for
global attributes, and URI + delimiter + elementLocalPart + delimiter
+ localPart for local attributes.

Using my ParserFilter approach, of course, no parsers need to change
at all to support namespaces: it becomes an *application* issue,
but supported by a *universal* piece of machinery.  Ditto with
inherited attributes generally.
