I don't know of Michel's STM DTD, but from his description it sounds
as if he's simply using a subset of XTM. There'd be no harm in that,
nor would it change the underlying model.

If STM is a *new* syntax, then what Michel needs is the RM in order
to define his syntax. If the RM has any use, it'd then be a rather
simple matter of transforming STM to XTM, or STM to Hytime. In
fact, it'd not be a bad idea to consider writing Linear Topic Maps
as a legitimate expression of the RM rather than simply an
authoring syntax.

Unless I'm misunderstanding something fundamental, which is
certainly possible at this point...
