Hi webkit-dev:

This is a request for WebKit's position on Capability Delegation.

Capability Delegation defines a mechanism through which a script can delegate its ability to call a restricted API to another browsing context it trusts.  Through this mechanism, Chrome is looking into supporting Payment-Request processing in a cross-origin iframe as detailed in the explainer.
Thanks.
