Dear Authors, et. al,
please kindly consider my comments to the current version of the draft:

   - I suggest not to introduce persistent mode for what otherwise
   characterized as on-demand OAM, e.g. ping and traceroute. Instead, consider
   using LMAP architecture with Controller, Measurement Agent, and Collector
   roles/elements, and, specifically, draft-ietf-lmap-yang
   <https://tools.ietf.org/html/draft-ietf-lmap-yang-11>
   - What is the need to use tp-attribute-type and tp-attribute-value
   which, in my view, provide partial technology-specific list even though the
   model claims to be technology independnet.
   - Again, the CL OAM methods model uses some LSP ID but comes short
   referencing draft-zheng-mpls-lsp-ping-yang-cfg work.

Regards,
Greg
