Maintenance should be done on it's own branch. The maintenance branch
should branch from the tag.

Working directly on the tag is bad because:
        - the tag is supposed to be a known baseline. By developing in
the tag, anyone who tries to use the tag gets random code. Random code
is bad, but only because customers don't like paying for random code,
which makes it difficult for your company to pay you.
        - if you start a patch in the tag, what do you do when a 2nd
more critical tag needs to go out first?
        - tags exist to help make branching or research easier. If I
see tags/prod.1.0, I expect it to be 1.0, not 1.0 plus two maintenance
patches.
        - if you do update a tag, you're morally, legally, and ethically
obligated to warn everyone that if they checked out the tag previous to
your change, they need to run 'svn update', or worse, re-do and
re-deliver their work to pick your change.

You might want to look at the tools/contributed software and see about
limiting write access to the tags directory.
