Proposed resolution (January, 2014):

Change the grammar in 9.2.9.5 [dcl.type.elab] as follows:

    elaborated-type-specifier:
      class-key attribute-specifier-seqopt nested-name-specifieropt identifier
      class-key simple-template-id
      class-key nested-name-specifieropt templateopt simple-template-id
      enum nested-name-specifieropt identifier

The grammar for elaborated-type-specifier in 9.2.9.5 [dcl.type.elab] reads, in part,

    elaborated-type-specifier:
      class-key nested-name-specifieropt templateopt simple-template-id

This allows use of the template keyword without a nested-name-specifier, e.g., struct template S<int>. This is inconsistent with other uses of the template keyword. It might be better to split the production in two and only allow the keyword following a nested-name-specifier, i.e.,

    elaborated-type-specifier:
      class-key simple-template-id
      class-key nested-name-specifier templateopt simple-template-id
