Example: A Salesforce user locates a slide deck in the Nuxeo repository. The user wants to customize this slide deck for a particular prospect. But of course they do not want to modify the original.
Presumption: Direct Edit or Live Connect is the best way to handle the editing. I'm not asking to build a content editor delivered by Nuxeo within Salesforce.
So in some ways to feature is to search for a document, make a copy of that document, and be able to edit the copy.
