Better description for 'keywords' property

>From previous conversations on this list, it looks like
http://schema.org/keywords is meant to hold a list of comma-separated
keywords, like the RDFa on this page:
http://arc.lib.montana.edu/msu-photos/item/286:

<span property="keywords">john burke, msc, football, team</span>

If this is correct, the description for this property, which currently
reads "The keywords/tags used to describe this content", could be a bit
more detailled. I suggest:

A comma-separated list of keywords/tags used to describe this content.
