Mandatory Attributes

[PrathibaJee]

The latest UML2YANG tool will include mandatory substatement to attributes that has "Multiplicity 1 + no default values defined". The following attributes which are formerly optional will be changed to mandatory in the upcoming YANG.

Further , if an attribute is decided to be optional , we shall handle it in the UML modelling by either introducing a default value or by modifying the Multiplicity to 0..1.

S.No	Grouping/Datatype	Attribute	Mandatory	Optional
1	object-creation-notification	object-id-ref
2	object-deletion-notification	object-id-ref
3	available-queue-type	queue-name	X 1)
4	queue-depth-type	queue-name
5	per-hop-behavior-type	queue-name	X 2)
6		drop-precedence-inside-queue
7	egress-per-hop-behavior-to-priority-bits-mapping-type	mapping-number	X 3)

1. It is a key attribute of qos-profile-capability/available-queue-list
2. It is a key attribute of qos-profile-configuration/ingress-8021p-to-per-hop-behavior-mapping-list, ingress-exp-to-per-hop-behavior-mapping-list, ingress-ip-dscp-to-per-hop-behavior-mapping-list
3. It is a key attribute of qos-profile-configuration/egress-per-hop-behavior-to-8021p-mapping-list, egress-per-hop-behavior-to-mpls-exp-mapping-list, egress-per-hop-behavior-to-ip-dscp-mapping-list
