That depends on what you mean by "distinguish" and what you (or Roger)
mean by "XML Vocabulary".

an xhtml 1.1 strict table has a different content model than an xhtml
1.1 transitional one, but both are represented by the element table in
namespace http://www.w3.org/1999/xhtml

Similarly an an xslt variable element has different attributes defined
in XSLT 1 and 2 but both use the element name variable in namespace
http://www.w3.org/1999/XSL/Transform
whether XSLT 1 and 2 are different vocabularies or different versions of
the same vocabulary is arbitrary depending on how you define the terms,
but they definitely use the same namespace.
