setIdAttribute* sets the ID-ness of the attribute, not its name.
Attribute methods on the Element interface that are manipulating
attributes without modifying don't have the INVALID_CHARACTER_ERR
exception (see getAttribute, hasAttributeNS, ...).  I would propose to
leave the specification as is and return a NOT_FOUND exception in case
of invalid character in the name.

done. (modulo other changes I did for Andrew Clover).
