Curiously, has anyone attempted to do meta-validation to
realize conditional validation ? (much along the same line of
thought as template metaprogramming in C++ to realize
conditional compilation)
What I mean is that can conditional validation be facilitated
through mechanisms such as "Substitution Groups"
and/or "xsi:type" ?
If, workflow/application states infoset are encapsulated as
elements with different specific types at different point
of the workflow/process rather than its state information being
encapsulated in the same type regardless of its processing
state, then I think, we can easily achieve conditional validation
with the current xsd semantics.
Any thoughts on this meta-validation approach versus say
dynamic schemas ?
