[regrep] Re: Support for External Repository Items

[Len Gallagher <LGallagher@nist.gov>]

Regrep members,

Attached is a revision of a proposal first distributed to this list on 
October 4. After comments to this list from Scott Hinkelman and personal 
off-line discussions with Nikola Stojanovic, it is clear that the attribute 
name "contentURI" is too ambiguous to be useful. This revised proposal 
changes it to "discoveryURL" in the Registry Information Model and changes 
it to "attachmentURI" when it is used in Registry Service XML elements for 
document submission or retrieval to reference a SOAP attachment.
