what's the verdict?

[Laura Hatcher <lhatcher@argoneng.com>]

I am a newbie to XML and I was looking for information about XML schemas
on the web.  I found a web site called XML Schemas: Best Practices and
they have a lot of recommendations, such as to use Chameleon namespaces,
but an article on xml.com preaches the opposite.  So I am interested
about what is the the best practice for namespaces and also the best
practice for using Types.  In my schemas I define a lot of abstract,
complexTypes and then refer to them using the venetian blind technique.
Is this bad?
