The logic of a validator is to check data against a DTD that you provide
(directly or indirectly). Nothing more, nothing less. Well, to be exact,
some validators also run some heuristic checks beyond that, causing some

The only thing that a validator will help in that is that you can use it
to check whether your documents comply with the DTD (the formalized part
of the syntax) of the version of XHTML that you regard as standard.

The validator only reports compliance of your document comply with the DTD
that you specify. It does not require anything. _You_ specify the
requirements (the DTD), and the validator checks, upon your request,
whether they are fulfilled.

And what would happen when style sheets are not in use? Besides, there is
no CSS unit corresponding to "average width of a character", and even
specifying so-and-so many rows using CSS requires some care. So CSS has
in fact less "functionality" here than CSS. But these issues have nothing
to do with validation.
