Technically I think "mixed content" is a property of an element type in a
schema or DTD, it is not a property of an instance. Given an instance such
as <a>xyz</a> or <a><b/></a> you can't actually tell whether the schema/DTD
allows mixed content or not.

But at the instance level you can test whether an element has both
(non-whitespace) child text nodes and child elements using test="* and
text()[normalize-space(.)]".
