Yes, anyone can contribute.  From the POSIX document itself:
http://pubs.opengroup.org/onlinepubs/9699919799/frontmatter/preface.html

"Anyone wishing to participate in the Austin Group should contact the
chair with their request. There are no fees for participation or
membership. You may participate as an observer or as a contributor. You
do not have to attend face-to-face meetings to participate; electronic
participation is most welcome. For more information on the Austin Group
and how to participate, see www.opengroup.org/austin."

I personally call in to the majority of the meetings (generally a 90
minute teleconference about 2 or 3 times a month), while others on this
list (such as Chet) take a more passive role and only subscribe to the
mailing list to read the meeting minutes and provide feedback when
directly asked how a potential change to the standard would impact
existing implementations.

The link you gave is the online version of POSIX 2008 (the .pdf is the
canonical version; the online rendition is for convenience); but you
should be aware that the Technical Corrigendum 1 for POSIX 2008 is due
out later this year.

This is one of the bugs that was approved for inclusion in the Technical
Corrigendum, currently under balloting (you can see the full list of
bugs that will be folded into TC1 by filtering the list to those bugs
with the 'tc1-2008' tag).

Assuming balloting goes well, it will be later this year, but bash
proactively already implemented it.
