Nope, nope, nope.  Consider this:

<STYLE type="text/css">
	foo:p {ident 1em}
</STYLE>  <!-- or substitute however you like to embed stylesheets -->
<foo:p xmlns:foo="http://some.net/ns-1">
This is a paragraph.
<foo:p xmlns:foo="http://some.va/ns">
John Paul II

The CSS stylesheet will blindly style both foo:p's, even though
they are semantically distinct ("paragraph" vs. "pope"), because the
stylesheet is global and the ns prefixes are local.

The only way out is to change the second "foo" to a different 
prefixes, making the whole idea of local prefix definition
