This is very interesting. Two questions. First, how stable is this? 
Should the namespace http://www.w3.org/2007/05/powder# change?

Secondly, how do I specify "all resources"? (In my case, some resources 
may use mailto: URIs, others may use UUID URIs.) Am I stuck with the 
following, or is there a shorthand representation?


And would the above also match resources that have no URI identifier 
(i.e. blank nodes)?
