Hi Haomian, WG, Note that, this guideline should be for any 'future' draft, since this update would have to use [I-D.ietf-pce-enhanced-errors] as a normative reference (as they will be providing details of Error-criticality and Propagation etc). For any 'mature' draft it is better to use [I-D.ietf-pce-enhanced-errors] as informative reference with details of error handling added into [I-D.ietf-pce-enhanced-errors] itself (as already done for some drafts).
Thus my suggestion would be to say - Error and Notification handling as per [I-D.ietf-pce-enhanced-errors] should be considered in PCE documents that include multi-PCE interactions. A requirement for the editors of these drafts is to evaluate the applicability of the procedure in [I-D.ietf-pce-enhanced-errors] and provide details about the "Error-criticality" TLV and "Propagation" TLV for errors and notifications defined in the draft. Examples of this can be found in section 5.4.3 of [I-D.ietf-pce-enhanced-errors]. Thoughts? Thanks!
