[@sheet] Naming / Bikeshedding

[aluhrs13]

• The name nestedStyleSheets is up for discussion.
• Should we add name to the StyleSheet interface or overload the existing title attribute instead?

Is there a specific author use case for something with the shape of nestedStyleSheets? The reason I ask is that it's incongruous with how other at-rules are represented in the CSSOM. I would expect to see @sheet represented by an interface derived from either CSSRule or perhaps CSSGroupingRule, for example:

// Deriving inspiration from CSSImportRule
interface CSSSheetRule : CSSRule {
    [SameObject] readonly attribute CSSStyleSheet? styleSheet;
    readonly attribute CSSOMString name;
}

Or:

// Deriving inspiration from CSSMediaRule
interface CSSSheetRule : CSSGroupingRule {
    readonly attribute CSSOMString name;
}

Then authors can reach the sheets/rules and manipulate them in the OM using existing methods on CSSStyleSheet.
