Proposed resolution (August, 2011):

Change 13.8 [temp.res] paragraph 8 as follows:

Knowing which names are type names allows the syntax of every template definition to be checked. No diagnostic shall be issued for a template definition for which a valid specialization can be generated.

No diagnostic shall be issued for a template definition for which a valid specialization can be generated. If no valid specialization can be generated for a template definition, and that template is not instantiated, the template definition is ill-formed, no diagnostic required. If every valid specialization of a variadic template requires an empty template parameter pack, the template definition is ill-formed, no diagnostic required. If a type used in a non-dependent name...
