Hi Jirka,

Thanks for your answer. Your proposal is a possible way to go, but we
have to keep the meaningful EOL delimiter after the mergemap
directive (or steal "xtm" and "ctm" from possible topic identifiers).


    %mergemap http://example.org/file

Could be interpreted as:
  a) mergemap directive followed by a topic with the id 'xtm'
  b) mergemap directive using XML syntax

If we keep the meaningful EOL delimiter, the interpretation would be
(a) in all cases. If we steal "xtm" and "ctm" from the possible topic
identifiers (b) is the solely interpretation.
