# 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.
