Name

The element name must correspond with the augmented type name, with the "Type" representation term being replaced by "Augmentation".

The Immigration domain augmentation container element for nc:PersonType is "im:PersonAugmentation".

Substitution group

The element must be declared to be substitutable for an augmentation point element.

im:PersonAugmentation (augmentation element) is substitutable for nc:PersonAugmentationPoint (augmentation point).

Augmentation Type

An augmentation container element must have a corresponding augmentation type.

Augmentation element im:PersonAugmentation has augmentation type im:PersonAugmentationType.

Name

The type name must correspond with the augmented container element name, with the addition of the "Type" representation term.

Augmentation element im:PersonAugmentation has an augmentation type with the name im:PersonAugmentationType.

Parent type

An augmentation type must extend structures:AugmentationType.

Augmentation type im:PersonAugmentationType extends type structures:AugmentationType.

No further augmentation points

Each augmentation element should replace the augmentation point of the original type. Augmentations of augmentations are not allowed.

• Augmentation type im:PersonAugmentationType should not contain its own augmentation point element like im:PersonAugmentationPoint.
• Any substitutions from other namespaces should be made directly on the original augmentation point element for nc:PersonType - nc:PersonAugmentationPoint.
