Hi John,

That's right. "Validation Rules" are all about validating the instance
document with respect to the schema. The rules that govern the content
of the schema itself are the "Schema Component Constraints" (which
govern the logic of the schema) and "Schema Representation
Constraints" (which govern what an XML representation of a schema
looks like).

I'm not sure what the formal definition of "locally valid" is, but I
think it means the validity of the attribute in and of itself rather
than in the wider context (e.g. what element it's on).
