Would you expect any xml instance to be changed by a validation process?

A transformation task? Not a validator?
NVDL despatches certain parts of an instance to a validator.
Not to a part of your system.

Nor would Jing or any other validator? It's not their job in life Bryan.

I wouldn't expect to use a validator as a sax filter? They why should I 
ask a validator to do a filters job?


Quote. 19757:4
This part of ISO/IEC 19757 specifies a Namespace-based Validation 
Dispatching Language (NVDL). An NVDL
script controls the dispatching of elements or attributes in a given XML 
document to different validators,
depending on the namespaces of the elements or attributes. An NVDL 
script also specifies which schemas are
used by these validators.
