An HTMLCollection is a list of nodes. An individual node may
be accessed by either ordinal index or the node's name or
id attributes. Collections in the HTML DOM are assumed to be
live meaning that they are automatically updated when the underlying
document is changed.
See also the Document Object Model (DOM) Level 2 HTML Specification.
