Location groups as sidebar navigation
A location group can be used to define navigation items that appear in the sidebar. As an example, consider the claim Loss Details page in the following diagram:

This is a location group
defined in ClaimLossDetailsGroup
as follows:

Inside this location group, there are multiple LocationRef elements defined,
each one specifying a location.
As ClaimCenter displays this location, it notices that it is a location group, and automatically
creates sidebar items for each location within the group. Notice in this example that
the LocationRef elements referenced in this group correspond to the
items in the sidebar.
