| /** |
| * 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. |
| * <P> |
| * Note that this object models the actual entity, _not_ the entity |
| * declaration or the entity reference. |
| * <P> |
| * 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. |
| * <P> |
| * Quoting the 10/01 DOM Proposal, |
| * <BLOCKQUOTE> |
| * "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." |
| * </BLOCKQUOTE> |
| * 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. |
