- * <code>DTMNodeList</code> gives us an implementation of the DOM's
- * NodeList interface wrapped around a DTM Iterator. The author
- * considers this something of an abominations, since NodeList was not
- * intended to be a general purpose "list of nodes" API and is
- * generally considered by the DOM WG to have be a mistake... but I'm
- * told that some of the XPath/XSLT folks say they must have this
- * solution.
- *
- * Please note that this is not necessarily equivlaent to a DOM
- * NodeList operating over the same document. In particular:
- * <ul>
- *
- * <li>If there are several Text nodes in logical succession (ie,
- * across CDATASection and EntityReference boundaries), we will return
- * only the first; the caller is responsible for stepping through
- * them.
- * (%REVIEW% Provide a convenience routine here to assist, pending
- * proposed DOM Level 3 getAdjacentText() operation?) </li>
- *
- * <li>Since the whole XPath/XSLT architecture assumes that the source
- * document is not altered while we're working with it, we do not
- * promise to implement the DOM NodeList's "live view" response to
- * document mutation. </li>
- *
- * </ul>
- *
- * <p>State: In progress!!</p>
