You are confusing the original suggestion of using revision properties on
revision 0, with the one we now are discussing (suggested in

All Apache projects will have their own tag namespaces, defined as
non-revision properties on (typically) the project/branch directory. (The
proposed implementation stores tags pr branch, but now I think tags should
be stored pr project.)

Using non-revision properties makes them versioned.

Would you care to mention the difficulties with properties? All I can
think of is:
1. It is not possible to commit changes to single property on a
2. It is not simple to search properties based on their values. Or sort
the properties based on their values.

That's the goal. I just have to figure out which designs you like. :-)
