Hi Marta!
Adding to ietf-alarms-x733 from the ITU specs.
Could look something like this:

  augment /al:alarms/al:alarm-list/al:alarm:
    +--ro event-type?                event-type
    +--ro probable-cause?            uint32
    +--ro probable-cause-string?     string
    +--ro threshold-information
    |  +--ro triggered-threshold?   string
    |  +--ro (threshold-level)?
    |  |  +--:(up)
    |  |  |  +--ro up-high?         observed-value
    |  |  |  +--ro up-low?          observed-value
    |  |  +--:(down)
    |  |     +--ro down-high?       observed-value
    |  |     +--ro down-low?        observed-value
    |  +--ro arm-time?              yang:date-and-time
    +--ro monitored-attributes* []
    |  +--ro id?      al:resource
    |  +--ro value?   string
    +--ro proposed-repair-actions*   string
    +--ro trend-indication?          trend
    +--ro backedup-status?           boolean
    +--ro backup-object?             al:resource

Question to you, additional-information, that super generic thing. Do you think it is useful?
How should the definition look like…
AdditionalInformation ::= SET OF ManagementExtension
ManagementExtension ::= SEQUENCE
 {
  identifier  DMI-EXTENSION.&id({ManagementExtensionSet}),
  significance  [1]  BOOLEAN DEFAULT FALSE,
  information [2]  DMI-EXTENSION.&Value({ManagementExtensionSet}{@.identifier})
}

We could have a list with leafs identifier string, significance boolean and information string ?
Would it add any value?

Do you still think the security attributes are useful?
Br Stefan

Or do you view these attributes as outside of the IETF CCAMP scope (and therefore if someone needs these particular attributes they can augment the IETF CCAMP YANG?  I am attempting to understand the boundaries of what CCAMP intends to cover.
