from comment #0:
> Clause 1.3.2 of Schema Component Constraint: Derivation Valid
> (Restriction, Simple) in section 3.14.6 of Structures reads:
> 
>     1.3.2 If there is a facet of the same kind in the {facets} of the
>     {base type definition} (call this BF), then the DF's {value} is a
>     valid restriction of BF's {value} as defined in [XML Schema:
>     Datatypes].

from comment #3:
> For this bug, reference should be made specifically to the various schema

Perhaps a Note following the clauses of "Derivation Valid (Restriction, Simple)
which says:

   Note:  "Valid restriction" in clause 1.3.2 and 3.1.2.5 means that
   the facet in question satisfies the constraints given separately in
   the appropriate subsection of [reference to Datatypes 4.3] which
   describes that particular kind of facet.

Then no change to Datatypes is required.
