Hello Mr. van Kesteren

After shortly reviewing http://dev.w3.org/csswg/cssom/ we discovered 
that we still have trouble how page margins in page rules will be 
represented in CSSOM.

The current CSSPageRule has no notion about page margins and simply 
returning just a CSSStyleDeclaration does not suffice since a page rule 
consists of alternating style declarations and margins according to 
http://dev.w3.org/csswg/css3-page/#page-selector-and-context:

page <http://dev.w3.org/csswg/css3-page/#page> :
       PAGE_SYM S* IDENT? pseudo_page? S* 
       '{' S* [ declaration | margin ]? [ ';' S* [ declaration | margin ]? ]* '}' S*
       ;

As far as I see, currently there is no concept for enumerating 
alternating style declarations and margin rules, is there?

Furthermore we probably will also need an om-representation for margin 
rules then, which should not be to difficult, will we?

Something like

interface CSSMarginRule : CSSRule <http://dev.w3.org/csswg/cssom/#cssrule> {
           attribute DOMString margin <http://dev.w3.org/csswg/cssom/#cssstylerule-selectortext>;
  readonly attribute CSSStyleDeclaration <http://dev.w3.org/csswg/cssom/#cssstyledeclaration> style <http://dev.w3.org/csswg/cssom/#cssstylerule-style>;
};


Have these issues already been adressed in an internal discussion or 
have they only been unattended so far?

Best regards,

Ludger
