Operators' policies and procedures seem to differ significantly. If you read the OEM documentation strictly, it seems Airbus want you to treat it like a regular MEL item.

HANDLING OF MAINTENANCE MESSAGES DISPLAYED ON ECAM STATUS PAGE
At the head of each ATA chapter of this MEL, the related MAINTENANCE messages which may be displayed on ECAM STATUS page are listed with the indication of the associated dispatch status.
A MAINTENANCE message indicates the presence of a category of failure which can only be identified by the interrogation of CFDS.
Operators must implement procedures to manage MAINTENANCE messages and associated CFDS messages, to handle faults recording and repair within the rectification interval of category C (10 days). All MAINTENANCE messages have a rectification interval C except the following messages : DAR, DMU and QAR which have an interval D.
Dispatch with a MAINTENANCE message displayed on ECAM STATUS page is allowed without specific conditions except for the following messages :
- AIR BLEED : Refer to MMEL 36-00-01.
- DMC 1/3: Refer to Item 31-00-05 DMC 1/3 MAINTENANCE Message
- DMC 2/3: Refer to Item 31-00-06 DMC 2/3 MAINTENANCE Message
It is left to the operator to define the role devoted to flight crew and/or maintenance personnel in these procedures.
regards, FD.
