That's so much for the most helpful reply, Curt. I've been struggling with the modularization spec, trying to use the approach described there, but wasn't confident I was on their right track. Never managed to find the url you sent I'll dig into that further tomorrow. But I'm confused by the encouraging tone of "you could use an import statement and an appropriate namespace declaration to allow you to use XHTML elements and constructs in your schema, so you could say <ile:page> can contain specific elements or groups from the XHTML schema" and the discouraging tone of the closing one re "annotated XHTML". The former sounds like just what I want, and that the technique described in the Modularization spec will get me there eventually, regardless of what the XHTML designers planned for. Is that correct? The other confusion is why this is proving so difficult. I thought that problems like this were exactly what XMLSchema was designed for but I've found absolutely no success stories out there. It does seem to be possible, but man, its a bitch. >On Jan 23, 2004, at 7:00 AM, Brad Cox wrote: > >>Its been a week so I thought I'd better resend this. Could someone >>please respond?
