To repeat what I said on IRC: given your input, you can't produce the
above tree; what you can produce is

        { "domain"
          { "LOCAL"
            { "foo" = "bar" } } }
        { "domain"
          { "LDAP"
            { "foo" = "bar" } } }

The difference won't matter much to users of the tree - they can still
talk about '/domain/LDAP/foo'.

To do the actual splitting, save the attached file 'split_test.aug' and
run it through augparse.

            [ key word ] . dels "]" ]


  test l get "[domain/LDAP]" = ?
