This operation can be used to create top-level topological links as well as intra-subnetwork topological links.

The behaviour of this operation should be the same as if an EMS user were to attempt to create a topological link (or equivalent operation) at the EMS user interface.
Therefore, the specific conditions under which the creation is rejected are left to the EMS implementation.

Note: It is at the discretion of the EMS to delete topological links created by the NMS, as the owner of the topological link is the EMS, not the NMS.

Operation Exceptions:
1. NOT_IMPLEMENTED - Raised when the EMS does not support this operation.
2. INTERNAL_ERROR - Raised in case of non-specific EMS internal failure.
3. INVALID_INPUT - Raised when input parameter are syntactical incorrect.
4. OBJECT_IN_USE - Raised when the TL creation is rejected due to an aEndTP/zEndTP conflict.
5. ENTITY_NOT_FOUND - Raised when aEndTP or zEndTP do not exist.
6. UNABLE_TO_COMPLY - Raised when the creation is rejected based on EMS own criteria.
    Raised when the EMS is unable to execute the request because at least one of the parameters although valid could not
    be set and that parameter is identified as "not best effort" in additionalInfo.
    Raised when the creation is not possible because the EMS cannot comply for a reason different from the ones above.
    If the EMS cannot determine the reason it could not comply, it is also allowed to throw UNABLE_TO_COMPLY.
7. USERLABEL_IN_USE - Raised when the userLabel uniqueness constraint is not met.
