Igor, you probably have an older version:

+-------------+-----------------------+---------------------------+
         |Path Comp.   | Path Computation pre  |                           |
         |             | service provisioning  |     ietf-te.yang          |
         +-------------+-----------------------+-------------------------

Moreover in 5.2 : "   For path computation, [I-D.busibel-teas-yang-path-computation]
   presents now only use cases but YANG model work is also under
   consideration to provide statelss path computation RPC.  There is
   currently ongoing discussions on how to provide such a function using
   the TE tunnel model defined in [I-D.ietf-teas-yang-te] as a base."

There is no explicit mention of the compute_only solution , since , as you know, also RPC solution will be supported together with compute_only.
We did not provide specific details.

Thanks
Sergio (as co-author)

Hi,

In the 4.4<https://tools.ietf.org/html/draft-zhang-ccamp-transport-yang-gap-analysis-00#section-4.4>.  Function Summary and Related YANG Models, I read:

+-------------+-----------------------+-----------------------+
         |Path Comp.   | Path Computation pre  |                       |
         |             | service provisioning  |      NONE             |
         +-------------+-----------------------+-----------------------+

I disagree with this assessment. TE tunnel model defines the COMPUTE_ONLY mode explicitly designed to be used  to support Path computation NBI.

Cheers,
Igor
