 Asir,
 when using the word "restriction" I think I meant that any data
serialized according to the restriction MUST be a valid
serialization of the data according to the "unrestricted" rules
while it may not be true the other way around.
 While SOAP Encoding (the particular encoding) does not
explicitly allow subsetting, I can imagine other data models and
encodings to allow it.
 But still, unless somebody brings up a valid and important case,
I think we can siplify SOAP here. 8-)
