No, what I suggest is simply that svn:mergeinfo contains all path@rev
which have been merged into that path directly (but not indirectly).
For example, if you have
trunk@30 has svn:mergeinfo = branch1@1-20
branch1@25 has svn:mergeinfo = branch2@1-7
branch1@30 has svn:mergeinfo = branch2@1-10
and then you merge branch1@26-30 into trunk as r31,
then, according to my proposal, you get simply
trunk@31 has svn:mergeinfo = branch1@1-20,26-30
but NOT (as currently, if I understand it correctly)
trunk@31 has svn:mergeinfo = branch1@1-20,26-30;branch2@8-10
and also NOT (as your interpretation)
trunk@31 has svn:mergeinfo = branch1@26-30
Cheers,
Folker
