Neither.

XML Schema Documents can define a grammar for a language that
applications (including people) can imbue with meaning.

The same is true for other syntaxes, such as RDF/Turtle, RDF/N3,
RDF/XML.  The existence of the last of these is a proof that, if RDF can
convey semantics, and if an RDF graph, once transmitted over RDF/XML,
and reconstituted, still has the same semantics, RDF/XML can contain
semantics, and therefore XML can contain semantics (and so can ASCII,
and so can ethernet electrical signals...).
