[Voted into WP at March, 2010 meeting.]

Proposed resolution, October, 2009:

Change 9.12.1 [dcl.attr.grammar] paragraph 3 as follows:

...A If a keyword (5.11 [lex.key]) or an alternative token (5.5 [lex.digraph]) that satisfies the syntactic requirements of an identifier (5.10 [lex.name]) is contained in an attribute-token, it is considered an identifier...

9.12.1 [dcl.attr.grammar] paragraph 3 specifies that keywords can be used as attribute-tokens. However, the alternative tokens in 5.5 [lex.digraph], such as bitor and compl, are not keywords. The text should be changed to make the alternative tokens acceptable as attribute-tokens as well.
