[Whatwg] Are Web Applications Still a Vague Subject ?

[whatwg at appxweb.com]

 From the Working Group?s charter the first deliverable is stated as:
?A language evolved from HTML4 for describing the semantics of  
documents and applications on the World Wide Web. ???..?

Reading the draft specification and other related documentation a  
number of fundamental questions relating to the application part of  
this deliverable remain unclear to me.  So I don?t waste the groups  
time and can contribute productively, can anyone point me to the  
previous discussion threads or parts of the specification which gives  
answers or guidance to the following questions.

1 Is there an accepted definition of ?document? and ?application??
(Depending on the answer the remainder of these questions may be  
irrelevant. eg if application really means a ?form?. The last  
paragraph of Section 1.1 of the spec further confuses me, which is not  
difficult to do. )

2 When does a document become an application?

3 Is equal weight and priority given to addressing the requirements of  
documents and applications within the HTML5 specification?

4 Is there an accepted design basis for applications i.e. an  
Application Object Model (AOM)?

Kind Regards
