Thanks for the review and follow-through.

Aha, excellent catch.

I had assumed prior RFCs would be annotated to indicate when they had been superceded.  That is not the case (at this url at least).

Better way to check is

* RFC Editor
   https://www.rfc-editor.org

which indicates as you write above and leads to

* https://www.rfc-editor.org/info/rfc3550

Am thinking these are better URL addresses to use than the classic ietf.org/rfc addresses since they are authoritative and since the RFC Editor controls them.  Certainly more convenient for reader since latest status and multiple forms are provided for each RFC.

I am now going through many checks of all the RFCs, applying your change and a number of related ones.  This will appear later today.  Replying now FYI.

Thanks very much Christoph for excellent feedback.

Well this certainly remains a worthy agenda for applied research.

As far as the X3D specification goes, we only add references when they help explain requirements or guidelines in the specification.

As far as audio/video streaming goes, I think we will learn more (about audio at least) as we implement the W3C Audio API and corresponding Streams W3C Draft Recommendations.
