This is essentially how it is tagged in LaTeX. The conventional
output would be something like either

Theorem 2 Yadda, ...


Theorem 3.2 Yadda, ...

or some other variant, with Theorem in bold; however, depending on
the *definition* of <theorem>, other output is possible, eg, none,
different text for "Theorem", no number, ....

If you like, logically, this is a "Theorem", but what a "Theorem"
really is is defined elsewhere, and can vary according to the context.

%>Yadda, yadda, yadda<LEX element="paragraph", relationship="is a",

Where would "Theorem 3.2" come from?
