Yes, it's unique in a CPS instance, and it's the repository's job to 
give you a free one when you create a new document from scratch. The 
docid is basically a random integer, it has nothing to do with the 
getId() of the object visible by the user.

When you have a proxy (which is the main kind of user-visible object in 
CPS), you get its docid using proxy.getDocid().
