remember there are other schema languages, as well as ways to achieve
validation; RelaxNG, schematron, xslt, etc...can u upload link to that
paper? you dont *need* schemas to get useful work done, though it helps.

in the circles I traverse, W3C XML Schema is suffering from poor adoption.
Personally I think that XML Schema is more applicable to enterprise
domain type usage and doesnt scale 'down' well to simpler problem
domains....the truth is that most people want something simpler and get
a little frustrated on reading the specs.....I have yet to find a clear
tutorial on XML Schema that can teach a mid level developer to be useful
in XML Schema (any links would be appreciated).
I could make an analogy with the WS* stack, which I also think more
applies to enterprise scenarios though the reasons for poor adoption for
XML Schema are varied and no doubt different.
I only take XML Schema out if its box when I am in enterprise
development situations...in the past few years I have adopted Namespace
Resolution Language (NRL) to abstract the whole process, which I have
found to be *very* useful when dealing in situations where there are
many 3rd parties involved in development, all of whom have their own
approach to validation.
As an aside, NRL takes the sting out of managing multiple schema
validation approaches, and with its usage over the past year or so I can
see that there is great benefit to having multiple schema technologies.
