# Scope
|
||
|
||
USEF defines the content of XML messages between role processes, as required for implementation of USEF’s MCM.
|
||
Each message has a unique recipient, identified by the Internet domain and USEF role of the participant.
|
||
The message transfer mechanism is responsible for sending and receiving these messages.

<figcaption>Relationship between the normative USEF XML messages (yellow pane) and the best-practice message transfer mechanism (light-blue pane).</figcaption>
|
||
</figure>
|
||
|
||
When selecting a message transfer mechanism, local market conditions should be considered and the USEF privacy and security guidelines should be followed [^B5].
|
||
Further recommendations about the message transport mechanism are given in [Message transport mechanism](../appendix/message-transport-mechanism.md).
