The YANG clauses in IEEE Std P802.1ABcu includes the following in a "Internet Standard Management Framework" clause: " The YANG framework applies hierarchy in the following areas: 1) The uniform resource name (URN), as specified in IEEE Std 802d-2017. The structure of the URN is such that ieee is the root (i.e., name-space identifier), followed by the standard, then the working group developing the standard. " The description of the structure of the URN does not appear to match the URNs actually used, nor does is it agree with the specification in IEEE Std 802-d nor https://standards.ieee.org/wp-content/uploads/import/documents/tutorials/ieeeurn.pdf . Here are some examples of urn usage from published 802.1Q YANG modules: namespace urn:ieee:std:802.1Q:yang:ieee802-types; namespace urn:ieee:std:802.1Q:yang:ieee802-dot1q-types; namespace urn:ieee:std:802.1Q:yang:ieee802-dot1q-bridge; namespace urn:ieee:std:802.1Q:yang:ieee802-dot1q-stream-filters-gates; This usage does agree with Clause 11 of IEEE Std 802-d.
