In what sense different? You have RELAX NG + Schematron and for
validation you use both schemas, but XML editor will probably use only
RELAX NG when doing code completition. What's the problem here?

Of breaking several best practices developed by markup community over
the years. For example: defining new markup language instead of reusing
existing, refusing schemas, ...

I'm wondering if all syntax changes that HTML5 makes couldn't be just
achieved by producing more strict SGML declaration for HTML. Does anyone
did such analysis? If not, I think that coming with a new grammar for
HTML5 is just an insane.

Which is IMHO wrong, because free prose is much more ambiguous then
formal definition in some well recognized notation as XML schema. I
think that having schema and 5 pages of prose to cover things which
can't be expressed in schema is much more better then having 50 pages of
prose and no schema at all. Until my validator and editor are able to
understand prose text I prefer having schemas or other similar rigor
formal definitions.
