Form-associated elements in the parsing algorithm

I noticed that association with the form pointer is no longer a step  
in the parsing algorithm and instead the parsing algorithm refers to
http://www.whatwg.org/specs/web-apps/current-work/#form-associated-element

This could be clearer if that section enumerated the elements that are  
form-associated. For example, I tell at a glance if the list matched  
the list at
http://mxr.mozilla.org/mozilla-central/source/content/html/document/src/nsHTMLContentSink.cpp#509
