Comment (by afercia):

 I'm not following closely the amazing work on the HTML processor so I may
 be missing something but I'm not sure I understand why non-conforming and
 obsolete HTML elements are being added to the processor.

 For example, the LISTING and PARAM elements are listed in the 'Non-
 conforming features' of the spec and 'must not be used by authors'.

 > https://html.spec.whatwg.org/#non-conforming-features
 > 16.2 Non-conforming features
 > Elements in the following list are entirely obsolete, and must not be
 used by authors:

 > listing
 > Use pre and code instead.

 > param
 > Use the data attribute of the object element to set the URL of the
 external resource.

 @dmsnell can you please expand a bit, when you have a chance?

 Also, since there are commits still referncing this ticket, I guess the
 ticket should stay open?
