I guess not, because repositories by definition don't share any relation, so
the two will be completely separated from each other. Just wondering, but why
do you even want separate repositories?

Export from one and import into the other. This completely removes the
connection between the code and the history and also the file/dir properties
(svn propset..), which you will have to copy in addition. Further, since the
history is disconnected, each 'tag' will be a fully separate copy even though
it shares lots of data with the former tag, but SVN's algorithm of storing
deltas won't detect this, so you should prepare for a rather big repository
for the tags. OTOH tags in the same repository are just copies which have a
small, constant size.

Well, if you were using an svn:externals reference into the same repository, I
would suggest replacing that reference with a normal copy when tagging. That
way you have defined results and the size overhead is also negligible.
