// - 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
