Too complex. Take a good close look at svnaccess.pl and the matching
svnconfig file in the contribs directory of the Subversion source tree. By
simply setting appropriate privileges for specific users for directories
with specific names, you can restrict their read, create, delete, and modify
permissions separately. This allows you to create "tags" that are stable
until the site administrator moves or deletes them, or to restrict write
access in other clever ways. And correctly implemented, the permissions will
apply both to local users, svnserve users, and HTTP users.
