//
//  This file is part of the internal implementation of the C++ XML DOM.
//  It should NOT be included or used directly by application programs.
//
//  Applications should include the file <xercesc/dom/DOM.hpp> for the entire
//  DOM API, or xercesc/dom/DOM*.hpp for individual DOM classes, where the class
//  name is substituded for the *.

/**
 * ParentNode provides the capability of having child
 * nodes. Not every node in the DOM can have children, so only nodes that can
 * should include this class and pay the price for it.
 * <P>
 * While we have a direct reference to the first child, the last child is
 * stored as the previous sibling of the first child. First child nodes are
 * marked as being so, and getNextSibling hides this fact.
