<dl>
<dt>{{domxref("DOMImplementation.createDocument()")}}</dt>
<dd>Creates and returns an {{domxref("XMLDocument")}}.</dd>
<dt>{{domxref("DOMImplementation.createDocumentType()")}}</dt>
<dd>Creates and returns a {{domxref("DocumentType")}}.</dd>
<dt>{{domxref("DOMImplementation.createHTMLDocument()")}}</dt>
<dd>Creates and returns an HTML {{domxref("Document")}}.</dd>
<dt>{{domxref("DOMImplementation.hasFeature()")}}</dt>
<dd>Returns a {{domxref("Boolean")}} indicating if a given feature is supported or not. This function is unreliable and kept for compatibility purpose alone: except for SVG-related queries, it always returns <code>true</code>. Old browsers are very inconsistent in their behavior.</dd>
