Thanks. Do you know of any specific references?

I noticed that the IDC use was briefly described in
http://www.controlplane.net/idcp-v1.1-ogf/draft-gwdi-nsi-idcp-2010-sep-01.pdf
as well.

I have not found a document describing the allowed characters in
perfSONAR/OSCARS/IDC (I'll be interested in that!)

I'm not sure whether or not a document was ever written with any further level of detail, unfortunately. The only requirement was that it follow the allowed characters from RFC 2141, and that it not have spaces. In practice, the URN fields have all been a-z, A-Z, 0-9 and ._-/
