ISSUE-45 (Extensible metadata): Do we need an extensible metadata hook?  
[Widgets]

http://www.w3.org/2008/webapps/track/issues/45

Raised by: Marcos Caceres
On product: Widgets

Krzysztof Maczyński recommended that we need some kind of generic extensible 
metadata hook. If there a use case for such a thing? can it be achieved in some 
other way?
