LIS — Metadata ports are ambiguous in WSDL

Problem : Metadata ports are ambiguous in WSDL:
The spec allows duplicate metadata to be served by different WSDL ports as
well as multiple ports that are not duplicates. However, the spec does not
specify a way for the client to determine which ports are duplicates and
which are true new metadata.

Suggested Solution:
Change the WSDL service name to reference a unique metadata instance, and
all endpoint bindings contained in that service would be duplicates. This
one to one mapping between a service name and metadata would basically
group duplicate ports into individual services. By retrieving one port
from all the services a client is guaranteed to receive all of the
metadata without retrieving duplicate information. This standard practice
would solve the problem and be in the confines of a valid WSLD schema.
