• Have a localServicesRouterDeployment.war, defining a root level tags element, e.g.:

  tags:
    # Tag definition with a description for documentation
    - name: examples
      description: Operations related to SP examples
  ...
  

• Then, have a anotherLocalServicesRouterDeployment.war, defining a root level tags element, which include a tag with identical name but different description e.g.:

  tags:
    # Tag definition with a description for documentation
    - name: examples
      description: Operations related to LSR examples
  ...
  

When deploying both the applications, the resulting OpenAPI document components element shows both the tag occurrences, with duplicated names:

---
tags:
- name: examples
  description: Operations related to LSR examples
- name: examples
  description: Operations related to SP examples
...

while the OpenAPI spec (see the tags element specification) states:
Each tag name in the list MUST be unique.
