I have no problem to put some replacement at build/deliver time for
replacements that are the same for each files; for example copyright is the
same for all the files and can be replace at build time.

But my need is that each file, once it is commited, gets a new version
(generated by some algorithm). We use this mechanism for database objects
and for auto-update mechanism on the client site.

As I said before, i am not blocked by not having such a feature.
I will install a double commit mechanism using hooks. My though was just
that if an expansion mechanism already exists in subversion, why not
extending it. The "only" need would be to be able to contribute to meta-data
with an external/plugin/contribution mechanism.

Thanks for your thoughts, I will put in place the double commit mechanism.
