This area is just horribly fuzzy. I'm pretty sure that for any of
{RDFS, XSD, RelaxNG, DTD} you can make assertions that can't be
made in the others. At least pairwise. Alternatively, you
*could* write a set of schemas that tried to do the same
things. But this would be unidiomatic at best... I'm not
really sure we're in content-negotiation territory at all here.
And as previously noted, to make things worse, it's not unusual
at all to have multiple schemas in the same schema language.
