 * Performance Enhancement.  The QName that was passed to the CMLeaf
 * constructor was always being copied, even though the CMLeaf objects
 * only existed during construction of a DFA.  In most cases the original
 * QName that was passed into the CMLeaf constructor continued to exist long
 * after the CMLeaf was destroyed; in some cases the QName was constructed
 * specifically to be passed to the CMLeaf constructor.  Added a second CMLeaf constructor that indicated the QName passed in was to be adopted; otherwise the CMLeaf constructor just sets a reference to the QName passed in.

    //  decl pool. The rewrite is done by buildSyntaxTree() which recurses the
    //  decl pool's content of the element and builds a new tree in the
    //  process.
    //
