If an old client is used on a newer repos, maybe it is time to upgrade;-)

Having a mispelled svn property that is noticed much later is also kind of
a bad user interaction.

That has been suggested, but I feel it is too strong and too late:

you cannot just send a warning from pre-commit, you can only abort the
commit, so there would be no way to put a non standard svn:* property,
which would be bad: for instance, I could use the old svn and set up the
repos for some new upcoming props (e.g. svn:need-lock) before the repos
soft is actually upgraded.

One could think that the repos could advertise the 'svn:*' properties that
it accepts... well that could also be a property;-)

So I think that a warning is fine, or an error with a force option.

The "reserved" stuff is more a suggestion on which I have no real
technical opinion.

From the implementation point of view, it is quite simple to implement
that in a client, but having the list of set properties with svnlook from
within pre-commit does not look that easy.
