        description:
        - The name of the l3out to associate with.
        required: true
        type: str
      schema:
        description:
        - The schema that defines the referenced l3out.
        - If this parameter is unspecified, it defaults to the current schema.
        type: str
      template:
        description:
        - The template that defines the referenced l3out.
        - If this parameter is unspecified, it defaults to the current schema.
        type: str
  state:
    description:
    - Use C(present) or C(absent) for adding or removing.
    - Use C(query) for listing an object or multiple objects.
    type: str
    choices: [ absent, present, query ]
    default: present
notes:
- The ACI MultiSite PATCH API has a deficiency requiring some objects to be referenced by index.
  This can cause silent corruption on concurrent access when changing/removing on object as
  the wrong object may be referenced. This module is affected by this deficiency.
