--- Comment #4 from Tim Mills <tim@cbcl.co.uk> ---
I suggest the following note be added.
NOTE:
As a consequence of these rules, for an expression E and type L, where
1. L is a list type, or L is a union type of which a list type is in its
transitive membership, and
2. (E instance of L) eq true
then
E castable as L
is false. For example xs:NMTOKENS("a b c") castable as XS:NMTOKENS is false.
Furthermore, if L is a list type with a mininum length facet of zero, ()
castable as L is false.
