Class DTMProxy

    java.lang.Object
      |
      +--org.apache.xalan.xpath.dtm.DTMProxy

public class DTMProxy
extends java.lang.Object
implements org.w3c.dom.Node, org.w3c.dom.Document, org.w3c.dom.Text, org.w3c.dom.Element, org.w3c.dom.Attr, org.w3c.dom.ProcessingInstruction, org.w3c.dom.Comment

**For internal use only** `DTMProxy` presents a DOM Node API front-end to the DTM model.

It does _not_ attempt to address the "node identity" question; no effort is made to prevent the creation of multiple proxies referring to a single DTM node. Users can create a mechanism for managing this, or relinquish the use of "==" and use the .sameNodeAs() mechanism, which is under consideration for future versions of the DOM.

DTMProxy may be subclassed further to present specific DOM node types.
