Yes, such as (:graphics: http://....jpg :) -- it doesn't *have* to use 
Attach:-ed images.

Or:

- treat graphic as a special case and instead of generating pagevar 
markup for pmwiki to parse, retrieve the pagevar value (if it exists), 
parse it and modify it along the lines you suggest, then let pmwiki 
parse the modified markup -- messy, but possible

- treat this as an edge case and don't try to deal with it at all -- if 
it occurs in practice, go back to the page defining the metadata to add 
a group prefix manually
