| /** |
| * The <code>DOMConfiguration</code> interface represents the configuration |
| * of a document and maintains a table of recognized parameters. Using the |
| * configuration, it is possible to change |
| * <code>Document.normalizeDocument()</code> behavior, such as replacing the |
| * <code>CDATASection</code> nodes with <code>Text</code> nodes or |
| * specifying the type of the schema that must be used when the validation |
| * of the <code>Document</code> is requested. <code>DOMConfiguration</code> |
| * objects are also used in [<a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-LS-20040407'>DOM Level 3 Load and Save</a>] |
| * in the <code>DOMParser</code> and <code>DOMSerializer</code> interfaces. |
| * <p> The parameter names used by the <code>DOMConfiguration</code> object |
| * are defined throughout the DOM Level 3 specifications. Names are |
| * case-insensitive. To avoid possible conflicts, as a convention, names |
| * referring to parameters defined outside the DOM specification should be |
| * made unique. Because parameters are exposed as properties in names |
| * are recommended to follow the section 5.16 Identifiers of [Unicode] with the addition of the character '-' (HYPHEN-MINUS) but it is not |
| * enforced by the DOM implementation. DOM Level 3 Core Implementations are |
| * required to recognize all parameters defined in this specification. Some |
| * parameter values may also be required to be supported by the |
| * implementation. Refer to the definition of the parameter to know if a |
| * value must be supported or not. |
| * <p ><b>Note:</b> Parameters are similar to features and properties used in |
| * SAX2 [<a href='http://www.saxproject.org/'>SAX</a>]. |

| * tree, or removing superfluous namespace declarations from each element. |
| * Note that this is limited to what can be represented in the DOM; in |
| * particular, there is no way to specify the order of the attributes in the |
| * DOM. In addition, Setting this parameter to <code>true</code> will also |
| * set the state of the parameters listed below. Later changes to the state |
| * of one of those parameters will revert "canonical-form" back to |
| * <code>false</code>. Parameters set to <code>false</code>: "entities", " |
| * normalize-characters", "cdata-sections". Parameters set to |
| * <code>true</code>: "namespaces", "namespace-declarations", "well-formed", |
