A conversation identifier is usually assigned by the initiator of a conversation. Conversations may only be initiated and terminated. Joining conversations has the effect of initiating new conversations. Conversations cannot be split; this instead has the effect of parallel activities on the same conversation or the initiation of a new conversation. Each message belongs to only one conversation. Conversation scopes are defined in the business process definition.</xsd:documentation>
