I believe that this is a spec usability issue. To understand this, users
must read

- Attribute Decl Schema Component (section 3.2.1)
- XML Representation of Attribute Decl (section 3.2.2)
- Constraints on XML Representation of Attribute Decl (section 3.2.3)
...
- And, Schema for Schemas (Appendix A)

before they can compose a valid schema. Many users bumped into the same
issue.

The Constraints on XML Repr never duplicate what's in the sForS --
it's normative.
