This iptc URN namespace is made only for specification documents.
News items based on the IPTC standards NewsML 1 or NewsML-G2 may use the
"newsml" URN namespace for identifiers - http://tools.ietf.org/html/rfc3085

In this case a wildcard variant like
"urn:newsml:newsagency.com:20120101:news201206*" could express that all news
items issued by the News Agency with an identifier matching this wildcard
are covered by this policy.

But we have to be careful not to mix this up with ISSUE-11 which requests to
let assets point at a corresponding policy. That's why I proposed to add
this new "refTarget" asset/policy relationship for this ISSUE-11 use case,
while this "group of assets" policy could use the usual "target"
relationship.

Best,
Michael
