Description of issue: Self-contradictory text
Submitter name: Glen Zorn

Document: sip
Comment type: T
Priority: S
Sections: 4, 5.10
Rationale/Explanation of issue: Sections 4 & 5.10 appear to contradict
each other: Section 4 says "Central to the architecture is the fact that
the user data is stored in a single point in the network.  This
restriction does not mandate a particular implementation, e.g., it is
possible to implement clusters of databases operating in mirror mode to
provide redundancy.  The property required by this specification is that
the user data the Diameter Server has access to is stored safely in what
is seen, from the external point of view, as a single user database",
but section 5.10 says (in describing the process of finding the correct
Diameter server) "The Diameter SL, based on the contents of the SIP-AOR
AVP and its own routing tables, determines the Diameter server that
stores the information allocated to such user.  Then it builds a
Diameter LIA message (step 3) that includes a Result-Code AVP set to
DIAMETER_REDIRECT_INDICATION and one or more Redirect-Host AVPs, whose
values are set to one or more URIs of Diameter servers that store the
information related to such user.  Then the Diameter client in SIP
server 1 builds a new LIR message (step 4) addressed to any of the
Diameter servers received in the Redirect-Host AVPs".  It seems to me
that either there is exactly one Diameter server that stores data
pertaining to a given user or there is more than one.

Requested change: Make the document consistent; how this is done is up
to the authors.
