properties and property references.

WRT the property prefix, why not create a list of candidates and have
someone like Tab or Lea blog an article that we can all tweet/share and get
a straw poll?  I think potential candidates people have mentioned:

author- / auth-
.... any single char .... x-, a-, u-, c-, etc.

Maybe pick a few of those, provide a short arg for each (or link to them
here) and just straw poll to see what people think.
