Don't be silly.  The term “collection” always had a very distinct and 
special meaning with regard to browser APIs, pertaining to their interfaces 
(e.g., HTMLCollection and HTMLOptionsCollection).  The host object referred 
to by the ”style” property is _not_ a collection.

Like a true ignorant, you are attacking what you do not understand.

No, it is very relevant.  A DOM API is _not_ a part of the here-relevant 
programming language (that has changed from JavaScript 1.3 to 1.4 because of 
NES, but was never different with other ECMAScript implementations).

A script engine (such as SpiderMonkey, the script engine of Netscape/Mozilla 
JavaScript) could not care less about properties that DOM objects provide 
until those objects are accessed by program code.  The W3C DOM API has an 
ECMAScript language binding specified that allows its implementations to be 
used with ECMAScript implementations, for example JavaScript.  And a 
browser's *layout engine* implements the interfaces of that Specification
as (ECMAScript) *host* objects according to the language binding of the 
respective interfaces.

No, you still have not the least bit of a shadow a clue what you are talking 
about; sadly, that includes HTML (“<STYLE> tag”?).  And if your postings in 
this thread are examples of what the new FAQ is going to be, you should sure 
hope that you find many knowledgable people to help correct your many 
wannabe misconceptions, unless you want to have its readers unlearn even 
more than if they had read one of the many bad books out there in the first 
place.
