Re: [I2nsf] Request for WGLC on I2NSF YANG Data Models

Hi Linda,
No problem.
These WGLC on these two drafts are great!

Are you going to do WGLC on other interface data model drafts, such as
Consumer-Facing Interface, NSF-Facing Interface, and Registration Interface
together
or after WGLC completion of the Capability data model draft?

Thanks.

Best Regards,
Paul
