 If there is no location, does that mean the attribute is null? Should that be
 explicitly stated?

CSSOM says it must return null for embedded styles:

   http://dev.w3.org/csswg/cssom/#style-sheet-location


  The intended destination media for style information (media DOM 
  attribute)
  
  The media must be the same as the value of the element's media content 
  attribute.
 
 If the element's media content attribute is omitted, what should the 
 value of the attribute be? Should it be all (which section 4.2.6 
 defines as the default if the media content attribute is omitted)? Null? 
 The empty string (à la DOM reflection)?

Fixed.


 In any case, the definition above seems to conflict with the definition 
 of the media attribute in the CSS Object Model specification at 
 http://dev.w3.org/csswg/cssom/#stylesheet, which requires that the 
 attribute returns a MediaList.

I've fixed the section in HTML5 to not override the CSSOM spec, but 
instead to just use the hooks defined in CSSOM (except for the disabled 
flag, which seems to be an error -- it seems like that one should just 
be initialised by the stuff we define for alternative style sheets.)


  The style sheet title (title DOM attribute)
  
  The title must be the same as the value of the element's title content 
  attribute, if the attribute is present and has a non-empty value. If 
  the attribute is absent or its value is the empty string, then the 
  style sheet does not have a title. The title is used for defining 
  alternative style sheet sets.
 
 Again, if there is no title, does that mean the attribute is null?

This is defined by CSSOM, but I've tried to make HTML5 clearer.

[whatwg] The StyleSheet object (section 4.2.7)

[Alex Bishop]

There's a few parts of the specification of the StyleSheet object 
defined in section 4.2.7 that are unclear to me.



The location (href DOM attribute)

For link elements, the location must be the result of resolving the
URL given by the element's href content attribute, relative to the
element, or the empty string if that fails. For style elements, there
is no location.


If there is no location, does that mean the attribute is null? Should 
that be explicitly stated?



The intended destination media for style information (media DOM
attribute)

The media must be the same as the value of the element's media
content attribute.


If the element's media content attribute is omitted, what should the 
value of the attribute be? Should it be all (which section 4.2.6 
defines as the default if the media content attribute is omitted)? Null? 
The empty string (à la DOM reflection)?


In any case, the definition above seems to conflict with the definition 
of the media attribute in the CSS Object Model specification at 
http://dev.w3.org/csswg/cssom/#stylesheet, which requires that the 
attribute returns a MediaList.



The style sheet title (title DOM attribute)

The title must be the same as the value of the element's title
content attribute, if the attribute is present and has a non-empty
value. If the attribute is absent or its value is the empty string,
then the style sheet does not have a title. The title is used for
defining alternative style sheet sets.


Again, if there is no title, does that mean the attribute is null?
