overview: |
  Set Delimiter tags are used to change the tag delimiters for all content
  following the tag in the current compilation unit.

  The tag's content MUST be any two non-whitespace sequences (separated by
  whitespace) EXCEPT an equals sign ('=') followed by the current closing
  delimiter.

  Set Delimiter tags SHOULD be treated as standalone when appropriate.  
tests:
  - name: Pair Behavior
