I think RTH's suggestion of using a "+" or similar symbol to indicate the root is a good one. Another possibility (not mutually exclusive with that one) is to have some shorthand like using ".." in a context where a URL is required to "do the right thing". (Obviously an issue here is in determining whether something is a URL or filename, so maybe something like "%.." or "-.." is needed.)

I think you're missing an important point about URLs.

It's an URL. If you want to add an extension, use the URL syntax!

RTH's suggestion should be +:something/here at least, or preferably some [a-z]+ before the colon. We already have svn:, http:, and svn+ssh:. There's no reason why we can't have tag: or root:

SVN developers: A question: How hard is it to add a new URL method to the current sources? Could we add, for example:

root:foo/bar  -> svn+ssh://gcc.gnu.org/svn/gcc/foo/bar
    (or whatever your working root is)

tag:foo/bar  -> (something)/bar
    ("something" is looked up in .svnrc by "foo")

There's no real need for this to live in svn itself.

I think a generic mapping solution can work for gcc and benefit other SVN users as well.
