This seems strange to me. If you have a release 15 how can you then release to that version
again?

What I think you might want to consider is rather that your developer "tagging" the commit
in the log message and automating moving it to your branch he should commit to trunk then
merge that committed revision to your release/15 branch.

Even more simple, if someone is working on release/15 why wouldn't they be committing changes
directly to that branch? This seems like the more common use cases.

Have you read the svn community guide on how they work there branching and release management?
 (though looks like there are some broken links there since http://subversion/docs/community-guide/releasing.html
isn't working.)
