// The following stuff has to be statically analyzed
// 1. readonly attributes
// 2. using setAttribute to register an event handler (this should be disallowed since it can be used like 'eval')
// 3. All methods properties assigned here are implicitly readonly
// 4. inheritance in this file is implemented by creating a new object for the prototype. Instead, the prototype object could be shared

// A combination of interfaces NodeList, NamedNodeMap, HTMLCollection
// implement a list of Nodes, accessible through names as well
