XML messages from the local message queue to the message queue of a remote

participant.

It contains minimal metadata (which is distinct from the common

metadata used for all other messages), allowing the recipient to

look up the sender's cryptographic scheme and public keys, and the

actual XML message, as transformed (signed/sealed) using that

cryptographic scheme.

sending this message. Upon receiving a message, the recipient

should validate that its value matches the corresponding
|
|
attribute value specified in the inner XML message, once un-
|
|
sealed: if not, the message must be rejected as invalid.
|

:ivar sender_role: The USEF role of the participant sending this

message: AGR, BRP, CRO, DSO or MDC. Receive-time validation

should take place as described for the SenderDomain attribute

above.

wrapper, as transformed (signed/sealed) using the sender's

cryptographic scheme. The recipient can determine which scheme
|

applies using a DNS or configuration file lookup, based on the

combination of SenderDomain and SenderRole.
