HTML Working Group Charter - Dependencies

I notice that the CSS Working Group is not listed under 3.1 Dependencies of
the current charter [1]. Since the draft CSSOM [2] and CSSOM View [3] are
listed as dependencies under HTML5 [4], I wonder if CSSWG should also be
cited as a dependency in the charter (in addition to or instead of being
listed under Liaisons [5]).

[1] http://www.w3.org/2007/03/HTML-WG-charter#dependencies
[2] http://dev.w3.org/csswg/cssom/
[3] http://dev.w3.org/csswg/cssom-view/
[4] http://dev.w3.org/html5/spec/Overview.html#dependencies
[5] http://www.w3.org/2007/03/HTML-WG-charter#liaisons

I also notice that HTML5 makes normative reference to three I-Ds under
development in IETF:

*Applications Area Working Group (appsawg)*

draft-ietf-appsawg-about-uri-scheme-00 [6]

*Web Security Working Group (websec)*

draft-ietf-websec-origin-06 [8]

[6] http://tools.ietf.org/html/draft-ietf-appsawg-about-uri-scheme-00
[7] http://tools.ietf.org/html/draft-hoehrmann-javascript-scheme-03
[8] http://tools.ietf.org/html/draft-ietf-websec-origin-06

*??? Working Group*

draft-hoehrmann-javascript-scheme-03 [7]

Should IETF or these IETF WGs also be listed under the charter's section 4
"Relationship to External Groups"?
