/**
* Elements represent most of the "markup" and structure of the
* document. They contain both the data for the element itself
* (element name and attributes), and any contained nodes, including
* document text (as children).
*
* Elements may have Attributes associated with them; the API for this is
* defined in Node, but the function is implemented here. In general, XML
* applications should retrive Attributes as Nodes, since they may contain
* entity references and hence be a fairly complex sub-tree. HTML users will
* be dealing with simple string values, and convenience methods are provided
* to work in terms of Strings.
*
* DeferredElementImpl inherits from ElementImpl which does not support
* Namespaces. DeferredElementNSImpl, which inherits from ElementNSImpl, does.
