And isn't that what ultimately XML is supposed to be? I don't remember seeing any associated "relational" or other data-wise description implicit in the definition of XML.

It is mostly a way of defining a set of data according to a set of rules that is not necessarily itself defined in XML. Hence the DTD and such. In a way, almost a re-hash of the old BNF, applied to data.

Not necessarily a replacement for databases. Be they relational, OO, hierarchical or whatever.
