Please look again. I did post a link to a collection of introductory
material, but one of your own links (the IBM one, for what its worth)
serves the purpose nicely.

Please pay particular attention to the last sentence.

But that isn't a DTD - it is, in fact, a description of how to create DTDs,
that being the main point of XML.
Perhaps some of the confusion here is because of the two-tier definition of
XML: a "well-formed" XML document consists of an arbitrary set of tags that
have appropriate behavior (matching start and end tags, proper nesting
etc.). A "valid" XML document consists of a specific set of tags that
conform to a specific DTD. In neither case, however, is there anything like
an "XML DTD", that defines the tagset for all possible XML documents.
