/**
* Entity nodes hold the reference data for an XML Entity -- either
* parsed or unparsed. The nodeName (inherited from Node) will contain
* the name (if any) of the Entity. Its data will be contained in the
* Entity's children, in exactly the structure which an
* EntityReference to this name will present within the document's
* body.
*
* Note that this object models the actual entity, _not_ the entity
* declaration or the entity reference.
*
* An XML processor may choose to completely expand entities before
* the structure model is passed to the DOM; in this case, there will
* be no EntityReferences in the DOM tree.
*
* Quoting the 10/01 DOM Proposal,
*
* "The DOM Level 1 does not support editing Entity nodes; if a user
* wants to make changes to the contents of an Entity, every related
* EntityReference node has to be replaced in the structure model by
* a clone of the Entity's contents, and then the desired changes
* must be made to each of those clones instead. All the
* descendants of an Entity node are readonly."
*
* I'm interpreting this as: It is the parser's responsibilty to call
* the non-DOM operation setReadOnly(true,true) after it constructs
* the Entity. Since the DOM explicitly decided not to deal with this,
* _any_ answer will involve a non-DOM operation, and this is the
* simplest solution.
