21, 23, 19 and 42 are mathematically concepts that are not (normally)
disputed 2+2 is always 4. Most topic maps consist of assertions that *can*
be disputed and there are very real requirements for being able to
distinguish what Party A asserts in their topic map and what Party B asserts
in their topic map both pre- and post-merge. IMO this cannot be ignored by
the topic map merging process and has to be supported both in the definition
of the merging process and in the representation of a merge directive in
XTM.
