One thing to be careful of if you are doing this for differences, is 
that an implementation is free to ignore the xsi:schemaLocation and 
xsi:noNamespaceSchemaLocation attributes, and supply it's own schema for 
use in validation.

I would definitely not treat these as special attributes.  Especially, 
xsi:type (which many B2B Standards, i.e. Core Components based standards 
are saying not to use).  xsi:type can be used to override and substitute 
another complexType definition in place of the one that was originally 
specified.  For many B2B situations, this allows deviation from the 
standard, and may allow for a completely different structure showing up 
than what has been defined.

Any possibility of setting it so that how these are treated is configurable?
