    - The name of the schema.

    - Use C(absent) for removing.
    - Use C(query) for listing an object or multiple objects.
    type: str
    choices: [ absent, query ]
    default: query
notes:
- Due to restrictions of the MSO REST API this module cannot create empty schemas (i.e. schemas without templates).
  Use the M(cisco.mso.mso_schema_template) to automatically create schemas with templates.
