A restriction of a built-in list datatype (NMTOKENS, IDREFS, ENTITIES)
resolved its base through neither the BuiltinType table (only the singular
NMTOKEN exists there) nor the user-type table, so it fell through to an atomic
string and length/minLength/maxLength counted characters instead of list
items, rejecting valid instances. The restriction base now resolves through
simpleTypeReference, which keeps the list variety.
XSTS #146: valid instances rejected 604 to 547, invalid instances accepted
582 to 555. Baseline updated; regression test added.
Refs #146, #129.
