That is okay, we expect that to be a rare circumstance.

The location of the store for REPOSITORY BRANCHES is expected to be an
absolute URL.  The location of the store for STANDALONE BRANCHES is
expected to be the relative URL '.'.

Inheritance, to me, suggests that a branch would use the first enclosing
repository, whatever that might be.  Relative URLs don't have that property.

As I mentioned earlier, the division is a matter of taste.  Your
concepts of STORE, BRANCH, and probably CHECKOUT are also divisible.

We need ways to describe the workflows we support.  That's the purpose
of terms like standalone checkout or bound branch.  Sorry that it is
confusing.
