Sorry, I thought I had fixed the message before I sent it this time.  This is the same message as before,
just with pre-wrapped text.


I was asked to forward this message to this address.  It was originally posted to
 xmlschema-dev@w3.org .  I never received any responses to it, other than the one asking me to forward
it to this address.

Subject: Omitted facet component restraint???

I've been reading through the three Schema specification documents over the past several weeks, and

I've noticed that what appears to me to be an accidental omission in the facet component restraints.

In the fractionDigits facet component, it is specified that the value must not be greater than that of 

totalDigits. But, since a new type being derived by restriction is supposed to further restrain the value-

space, it would also seem to follow that the fractionDigits facet of a particular type must be less than or 

equal to that of its base type. Otherwise, it would be possible to derive a new type by restriction that 

includes values that are not included in its base type. I don't see any such constraint anywhere in the 

specification, nor do I see any way that it could be derived from the existing constraints. Was this 

accidentally left out of the document? Or, was it omitted intentionally for some reason I do not see?
