[Voted into the WP at the March, 2011 meeting as part of paper N3262.]

Date: 2011-02-15.00:00:00

Proposed resolution (February, 2011) [SUPERSEDED]:

Change the grammar of 9.12.1 [dcl.attr.grammar] paragraph 1 as follows:

    balanced-token-seq:
      balanced-tokenopt
      balanced-token-seq balanced-token
Date: 2010-02-10.00:00:00

An attribute-argument-clause should be allowed to consist solely of (), i.e., with no balanced-token-seq. Furthermore, the grammar for balanced-token should make the balanced-token-seq optional. Both of these goals could be accomplished by making the balanced-token optional in the first production of the rule for balanced-token-seq.
