Is the intention to cover both "absolute" and "descendant" forms?

If schema-node path string are limited to the absolute form (which the
name 'schema-node _path_' suggests), perhaps say so. Here is an
attempt:

     "A schema-node path string for use in the YANG SID registry.

      A schema-node path is an absolute YANG schema node identifier as
      defined by the YANG ABNF rule absolute-schema-nodeid, except
      that module names are used instead of prefixes.

      This string additionally follows the following rules:

      o The leftmost (top-level) data node name is always in the
        namespace-qualified form.

      o Any subsequent schema node name is in the namespace-qualified
        form if the node is defined in a module other than its parent
        node, and the simple form is used otherwise. No predicates
        are allowed.";
