Hi Eddie,

Thanks for confirming the spec.

For now I fixed my local copy of schema for schema for my
purposes, but in general I have diffculties in understanding why
it stops short of taking that of base type into account for derivation
by restriction. It would seem more natural to use the intersection
of the two in the case of restriction.
