Help needed with a unique type of branch creation

Hi all,

Off of trunk in our repo are various directories. I am trying to branch a specific revision of two of the directories and am not being successful ... the branch is always off of the HEAD revision. Here's one attempt:

$ svn mkdir ^/branches/temp
$ svn copy -r 10000 svn://domain.com/trunk/dir-x svn://domain.com/branches/temp
$ svn copy -r 10000 svn://domain.com/trunk/dir-y svn://domain.com/branches/temp

I have tried to use the '@' operator for the revision, but that didn't help. I'd rather not branch the entire trunk due to it's size and mostly unneeded files.

Any insight/suggestions would be welcome.

Regards,
