Yes it's true adding new documentation here may be overkill, but yes it should say something (as a user I always find it helpful if the docs are more verbose than not). So per your suggestion, how about the simplified: "ISC supports a single port node with parallel bus and optionally Bt.656 support." and I'll remit the other statements. > > 'port' child node with child 'endpoint' node.
