[7.1] Web Services: Updates to Assigning Client/Endpoint Configs section

A review of section "3.5. Assigning Client and Endpoint Configurations" should be done.

A few things mentioned in the tracking sheet:

• 'Example Descriptor with Two Endpoints' -> 'Example Descriptor with Two Endpoint Configurations'
• There are links (titled "jbossws-jaxws-config") that point to an outside SVN source. This should either be removed completely, or should point to the schema file in the location that is shipped with EAP: EAP_HOME/docs/schema.
