Ah, I see. Then perhaps this is the reason that no one has gotten it to 
work for nxml-mode and its derivates (like nxhtml-mode). Those modes 
must look at the whole buffer to be able to check against the DTD.

Maybe this can be fixed by using an extra indirect buffer for the DTD 
checking ...

I will.

Yes, see above.

I can see your point. But I meant that if a mode where restricted to 
just a part of a buffer it would not be that bad. But there are no 
structures within Emacs to support that - or multi-mode might be a way 
to do it.
