  <descr><p>The <code>DOMImplementation</code> interface provides a
      number of methods for performing operations that are independent
      of any particular instance of the document object model.</p>

	<descr><p>The name of the feature to test (case-insensitive). The
	values used by DOM features are defined throughout the DOM Level 2 specifications and listed in
	the <specref ref="ID-Conformance"/> section. The name must be an
	    <termref def="dt-XML-name">XML name</termref>. To avoid possible
	    conflicts, as a convention, names referring to features defined
	    outside the DOM specification should be made unique by reversing the name of
	    the Internet domain name of the person (or the organization that the
	    person belongs to) who defines the feature, component by component,
	    and using this as a prefix. For instance, the W3C SVG Working Group
	    defines the feature "org.w3c.dom.svg".</p></descr>
