FYI: because the ballot to amend ISO/IEC 13250 has passed, the XTM 1.0 DTD is now a part of the ISO/IEC standard.

That means we shouldn't make distinctions in the future between "ISO 13250" and "XTM" (of the sort that I've seen in recent postings). BOTH the HyTime metaDTD originally published in the standard and the XTM 1.0 DTD are now equally parts of the standard. Each one provides an approved ISO/IEC mechanism for interchange of Topic Maps.

To avoid confusion, ISO/IEC JTC1/SC34 has adopted the practice of calling the original HyTime form "HyTM", in parallel with "XTM" for the later form.

SC34 has published a document by Michel Biezunski and Steve Newcomb that summarizes what we see as the differences between HyTM and XTM: http://www.y12.doe.gov/sgml/sc34/document/0277.htm. We expect therelationship between the two notational conventions to be further elucidated by revisions to the standards and by other work in progress in SC34. There is a graphic at http://www.y12.doe.gov/sgml/sc34/document/0278.ppt (or http://www.y12.doe.gov/sgml/sc34/document/0278.gif) that will be expanded into a full roadmap for the relationship among the various components of the Topic Map standardization project. We need to keep clear that the transfer serialzations are not the definition of Topic Maps: The standard is the definition. SC34 intends that the supplementary standards will clarify the meaning of Topic Maps without changing their essential nature. (We also recognize that other transfer serializations are possible, outside the standard.)

The explanatory text of XTM 1.0 remains as it was, where it was. However, we should remember that this is provisional text and that the definitive interpretation now will be progressed by SC34 as we fill in the roadmap.
