What is the idea behind clause (see below) ?

I don't understand why the facets should be limited to whitespace
since list facets obviously include length, among others.

Can soneone give me an example of such an invalid schema, since
I can't seem unable to create one which fails this test.

In Schema Part I 2nd edition section 3.14.6 (Constraints on Simple Type
Definitions) subsection Derivation Valid (Restriction, Simple) 
item 2.3.1 

2 If the {variety} is list, then all of the following must be true:
2.1 The {item type definition} must have a {variety} of atomic or union
(in which case all the {member type definitions} must be atomic).
2.2 (empty)
2.3 The appropriate case among the following must be true:
2.3.1 If the {base type definition} is the *simple ur-type definition* ,
then all of the following must be true: The {final} of the {item type definition} must not contain list. The {facets} must only contain the whiteSpace facet component.
