Subject: [topicmaps-comment] RE: [topicmapmail] XML Schema for XTM DTD
OASIS has no TM committees that deal with the interchange format of TMs or the definition of what it means to be a TM. That's all in ISO/IEC JTC1/SC34's territory. Since TM software doesn't care how TMs were created (that's on the other side of the interchange process), it shouldn't matter whether a TM editor used a schema or a DTD to validate. But if any current software does validate its input, it's going to validate against a DTD since that's how the interchange format is officially defined. At this point, the only test of a schema would have to be whether something that it thinks is valid is also recognized as valid by the DTD. But remember that having a valid XML file is not the same thing as having a meaningful TM. I can generate all sorts of things that XMetaL tells me are valid XTM files but which mean absolutely nothing to a TM browser (as I know from copious idiotic experience).

There are many use cases when a schema is necessary today - do we like this or not. We should not wait until all the "rest of the standard settles out". I think Max Voskob has posted a valuable draft yesterday. It looks quite reasonable as a schema. But I am not the XTM expert. Did anyone test it with a given XTM?
