WebID-TLS + Credentials

I'm a bit supporter of both.

Working on local issues, HbbTV is compatible with WebID-TLS from a device
layer (TV's).

Credentials has a significant role, and i commend the work and broader
undertaking.

Yet;

It's potentially important that WebID-TLS becomes interoperable for billing
purposes with other systems that may be best addressed using Credentials.

What is the current viewpoint on how these two standards may become
interoperable.
