For example, in the various activity diagrams, the generic "browser" would occupy one of the swimlanes. What would happen within this column, and in what order, will need to be the same for each payment method, I reckon. For the various class diagrams, there would be a package that expresses the scope of the W3C specification, which contains a set of classes with their respective sets of attributes.

This would indeed be very useful!
There's a giant collection of use-cases to go through.
Who could possibly spend all those cycles?

The WebCrypto++ Demo & Documentation took TWO full months creating plus several days of server work but it should probably be considered as research since it doesn't exist in the real world (yet).

BTW, it seems awfully hard getting detailed information about Google's and Apple's payment systems.
