This is good news about SVG.

After reviewing the options I am becoming one of those partisians.
Even though my inexperience with XPath is not making it easy. What is
easy is to see how the separation of model and view makes for a much
cleaner solution for complex applications, than the alternatives.

The rise of OOP has been a wonderful thing for systems development.
But OO modelling is not the solution to all problems.  Just like SQL
wasn't.  People are lazy, they learn one thing in school and stick
with it for a career.  By and large, the people you find on this (and
similar) mailing lists are not representative of that wider IT
community though. More publication on blogs and social media about
these issues will eventually help spread the word that you have to
have more than one tool in your chest.  Or spend you career on only
one type of solution.

I wish there was more focus on XML Schema 1.1 support.  I know that it
has been pointed out to me on this list (I think it was here) before
that XForms is about forms not about validation.  But what I am seeing
is that I have complex schemas defined and I am having to duplicate
that in constraints in the model.

Of course this is _my_ perspective but it seems to me that a schema
should be able to be referenced as _the_ model.  I am referring to
going beyond support for simpleTypes.  Support for complexTypes with
multiple substitution groups and asserts would be awesome.
