Re: XML Schema becomes a W3C Recommendation

Tim Berners-Lee's keynote was great and this is a good news that I have
been waiting for a while as someone involved in projects relaying on W3C
XML Schema: this is a most needed schema language that will be doing a
good job for many applications. 

The way it has been presented as the third component (with XML 1.0 and
namespaces in XML) of the foundation of the whole XML world is, IMO, bad
news though.

I won't go in detail over all this as they have been covered in other
threads, but just let me summarize why I think it's bad news:

A foundation, especially when composed of three pillars, isn't usually
something modular in which you can replace one of the components and I
don't think this is good neither for a) W3C XML Schema itself nor for b)
XML in general.

a) This is putting a lot of pressure and responsibilities on top of W3C
XML Schema that doesn't deserve it and would probably have had an easier
job without this pressure.

b) This is not good for XML as  b1) W3C XML Schema shouldn't be seen as
a general purpose schema language and is a threat for the diversity of
XML vocabularies and b2) schema languages are a kind of early binding
that is not always something to wish.

Anyway, kudos for the work done by the W3C XML Schema WG.
