M3UA - Clarification on RFC 1.3.2.1

*RFC4666*

1.3.2.1.  Support for the Transport of MTP3-User Messages

Fact (Quote): The M3UA layer provides the transport of MTP-TRANSFER
primitives across an established SCTP association between an SGP and an ASP
or between IPSPs.

QUERY: The RFC seems to suggest that "MTP-TRANSFER PRIMITIVE itself" is
transported between NODE-A & NODE-B; our belief is that the
"CONSEQUENCE(result)" of having acted upon a primitive is what is
transported - - meaning that the PAYLOAD passed over by the "MTP-3 User"
under the primitive "MTP-TRANSFER" is what gets transported.

COMMENT: In a LOGICAL sense, OF COURSE, it would mean that when AT THE
SENDING NODE, the "MTP-3    User" passes down a PAYLOAD to its LOCAL M3UA
(requesting for its TRANSPORT to the remote nodeB),     the M3UA does ACTION
this, & with help from SCTP, causes this PAYLOAD to be transported across.
At    the receiving node, the M3UA shall get the PAYLOAD from its local
SCTP, which it will in-turn    handover to the UL {"MTP-3 User at node B"}.
TO THAT EXTENT, use of the phrase "transports MTP-   TRANSFER PRIMITIVE" is
perhaps understandable, BUT the fact remains that it is confusing!!!

Any Comments please???

Aditi
