Subject: Can final="extension" for simpleType?

The Datatypes rec and the Schema for Datatypes do not allow the value
"extension" for the final attribute of a simpleType.

However, section 3.4.6 of the Structures rec (under Derivation Valid
(Extension)) says:

2 If the {base type definition} is a simple type definition, then all of
following must be true:
  2.1 The {content type} must be the same simple type definition.
  2.2 The {final} of the {base type definition} must not contain

It seems that 2.2 will always be true.  Is this an oversight?
