That's right. One paper I read referred to "semantics" and
"meta-semantics." That helps to clarify things somewhat, but it strikes me
as the same kind of distinction as "language" and "meta-language." It is
useful at first, but then when you try to come up with a precise
definition you realize that there is none. HTML is a meta-language and XML
is a language and vice versa. Similarly, as far as I can tell, what we
today call a semantic could be a meta-semantic tomorrow, if it gets
adopted in XML (e.g. the namespaces proposal).

So perhaps the best thing is to talk about the semantics of the markup (as
defined in the markup language) and the semantics of the marked up
document (as defined in the documentation for the document type).
