<P>[Voted into WP at March, 2010 meeting.]</P>



<P>9.13.1 [<A href="https://wg21.link/dcl.attr.grammar#3">dcl.attr.grammar</A>] paragraph 3 specifies that keywords can
be used as <I>attribute-token</I>s.  However, the alternative tokens
in 5.9 [<A href="https://wg21.link/lex.digraph">lex.digraph</A>], such as <TT>bitor</TT> and <TT>compl</TT>,
are not keywords.  The text should be changed to make the alternative
tokens acceptable as <I>attribute-token</I>s as well.</P>

<P><B>Proposed resolution, October, 2009:</B></P>

<P>Change 9.13.1 [<A href="https://wg21.link/dcl.attr.grammar#3">dcl.attr.grammar</A>] paragraph 3 as follows:</P>

<BLOCKQUOTE>

...<DEL>A</DEL> <INS>If a</INS> keyword (5.12 [<A href="https://wg21.link/lex.key">lex.key</A>])
<INS>or an alternative token (5.9 [<A href="https://wg21.link/lex.digraph">lex.digraph</A>]) that satisfies
the syntactic requirements of an <I>identifier</I> (5.11 [<A href="https://wg21.link/lex.name">lex.name</A>]) is</INS> contained in an <I>attribute-token</I><INS>,
it</INS> is considered an identifier...
