// - Modifications to link.href property are reflected in sheet property.
// - Less-used features of link: disabled
// - Less-used features of style: disabled, scoped, title
// - CSSOM-View
// - getComputedStyle(): requires default stylesheet, cascading, inheritance,
// filtering by @media (screen? print?), layout for widths/heights
// - Load events are not in the specs, but apparently some browsers
// implement something. Should onload only fire after all @imports have been
// loaded, or only the primary sheet?

// CSSPageRule
// These rules don't really make sense to implement, so CSSOM draft makes them

// CSSCharsetRule
// CSSUnknownRule
// These objects are considered obsolete by CSSOM draft, although modern
