TSAS — subscription as described in chapter 4 is specifying more than needed

subscription as described in chapter 4 is specifying more than actually
needed. It specifies also internal interfaces. For that reason we
propose to move
the overall subscription description into an annex and reduce the
current specification to only
these interfaces and segments that are necessary.
The information model (4.2) should be changed as follows.

Figure 4.2 subscription information model. This has allways created a
lot of discussion. We want to simplify the information model as it
currently does not
reflect the idl. Delete all inheritance, remove the attributes from the
figure, add a
1-to1 relation between subscriber and serviceprovider, adda 1-to many
relation between
subscriber and enduser, add a 1-to-many relation between enduser and
sag.
delete the groupmember relation

4.2.3 replace in serviceContract service Profile by ServiceTypeName
service_type,
ServiceTemplate service_template and PropertyList service_properties and
change
the textuel description.
This is a result of simplifying (removing the inheritance) from the
object model (figure).

4.2.6 replace ServiceTypeName service_type, ServiceTemplate
service_template
by ServiceContractId service_contact_id and change the textuel
description
This is a result of simplifying (removing the inheritance) from the
object model (figure).

4.2.7 delete last sentence of first paragraph "end-user", it is no
longer valid.

Replaced in document and the text is revised according to the changes
