Pete,

My only beef with the proposed additions are the "destination-attribute-collection" attributes.

We should just include Job Template attributes directly in the destination-uris and destination-uri-ready collections. Thus, it would just be:

    destination-uris
        destination-uri
        [number-or-retries]
        [retry-interval]
        [retry-time-out]
        [any Job Template attribute]

    destination-uri-ready
        destination-uri
        [destination-info]
        [destination-is-directory]
        [destination-name]
        [any Job Template attribute]

This would be consistent with how other attributes (job-sheets-col, covers, etc.) deal with embedding Job Template attributes in collection attributes.

If you really want to put the Job Template attributes in their own collection, call it "destination-attributes"; we never use "collection" spelled out in the name, and generally only add -col if there is already a non-collection form of the attribute (e.g. media and media-col, finishings and finishings-col, etc.)
