All successful formats that I know of have prose description that goes
beyond what is described by their schema/grammar/dtd.
It is both futile and undesirable to attempt to represent everything about a
format in a machine readable format. Unless of course you're looking to do

Could you be more specific?

That's right. Not in the near future, but the door is open for something

In an even more general way, it is possible to build validators for formats
by encoding the rules in the prose of the specifications (in addition to any
formal grammar/schema etc.) in a programming language (XSLT, Perl, etc.).
