-- NOTE When the Abort Message is generated by the Transaction sublayer, a p-Abort Cause must be

DialoguePortion ::= [APPLICATION 11] EXTERNAL
-- The dialogue portion carries the dialogue control PDUs as value of the external data type.
-- The direct reference should be set to { ccitt recommendation q 773 as (1) dialogue-as (1) version (1) }
-- if structured dialogue is used and to { ccitt recommendation q 773 as (1) unidialogue-as (2) version (1) }
