Subject: RSR-merge clarification


Perhaps you can clarify the description of the 'RSR-merge' element for me.

I understand that merge rule takes the 'ultimate' descendent of the 
versioned resource revisions selected, but the conflict case confuses me. 
 The doc (Clemm et al. versioning-01.1 May 17, 1999, 7.1.7) says:
     "If no selected revision is a descendent of all the
     other selected revisions, then a conflict has occurred,
     and the DAV:rsr-merge selects the first revision
     selected by an element in the sequence."

Do I choose ANY element in the sequence and pick the first revision 
selected?
If so this seems somewhat arbitrary.

I'd appreciate any insight to the intention.

Thanks
Tim

p.s.  I'm assuming that the trivial case of the merge rule constituents 
selecting only a single revision is a successful selection of that revision, 
without conflict.
