When Cross Database Joins were introduced in 10 all connections became "federated" by default, even if they weren't actually joined to anything else. 

In the file format that means they get represented as named-connection/connection elements. Expressed under one top-level connection element with a class of 'federated'.

Except for 'sqlproxy' connections (Published Data Sources) -- they stay in the old connection style as a top level connection element.

We need to, when in a 10.0 or greater workbook, get all federated connections (named-connection) plus go back and find any sqlproxy connections as well.
