<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-Compliance"/> 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>
