"A rose by any other name...". You can call them anything you
like ... it won't help. The tag _concept_ is more complex to present,
and it's _implementation_ is more complex to explain. Do you have any
experience of doing something like this? With trained, but non-

You have those now (per-dir access controls), so in fact it *might*
be possible, but the implementation isn't correct, since ad admin has
to "bless" a folder as a tags folder, which means just creating a
"tags" folder is not enough; so the user has no cues from the tool
about which "tags" folders are _really_ immutable and which should be.
If tags were really to work for me, I would need three additional
-- The ability to actually mark the tag as truly immutable, enforced
by the tools, at create time. Something like:
svn copy blah blah --immutable
-- The ability to create a tag (copy) at commit time in a single
svn commit blah blah --tag PATH
-- The ability to use a tag as an argument to the --revision switch:
svn co foo.c --revision "some-tag-path-syntax-or-other"
Whatever -- it's not going to happen anyway since the subversion
priests here don't need it, so ipso facto no-one else does either.
