Trying to use an unsupported feature

I have a sandbox which is just the trunk, which I try to tag. How can
I do that? I try

svn copy . <repo-url>/tags/<tagname>

This gives

svn: Trying to use an unsupported feature
svn: cannot copy path '' into its own child 'https://www.dcl.hpi.uni-potsdam.de/playground/tags/another'

I don't think I'm trying to copy a path into its own child here.

But if I do, how can I specify this copy operation?

Regards,
Martin
