Wouldn't a validatable format with a DTD
be more useful for storing data?

ie. plain vanilla XML?

Otherwise, aren't we advocating abandoning XML for a
another format? One that loses the ability to be
verified, except with the use of custom-written software.

In other words, if RDF is intended for storage of data,
what's XML for?
