 <P>
 Represents an extension namespace for XPath that handles java packages
  that may be fully or partially specified.
  It is recommended that the class URI be of one of the following forms:
  <pre>
    xalan://partial.class.name
    xalan://
    http://xml.apache.org/xalan/java (which is the same as xalan://)
  </pre>
  However, we do not enforce this.  If the class name contains a
  a /, we only use the part to the right of the rightmost slash.
  In addition, we ignore any "class:" prefix.
  Provides functions to test a function's existence and call a function.
  Also provides functions to test an element's existence and call an
  element.

 <DD>Process a call to a function in the package java namespace.
  There are three possible types of calls:
  <pre>
    Constructor:
      packagens:class.name.new(arg1, arg2, ...)

    Static method:
      packagens:class.name.method(arg1, arg2, ...)

    Instance method:
      packagens:method(obj, arg1, arg2, ...)
  </pre>
  We use the following rules to determine the type of call made:
  <ol type="1">
  <li>If the function name ends with a ".new", call the best constructor for
      class whose name is formed by concatenating the value specified on
      the namespace with the value specified in the function invocation
      before ".new".</li>
  <li>If the function name contains a period, call the best static method "method"
      in the class whose name is formed by concatenating the value specified on
      the namespace with the value specified in the function invocation.</li>
  <li>Otherwise, call the best instance method "method"
      in the class whose name is formed by concatenating the value specified on
      the namespace with the value specified in the function invocation.
      Note that a static method of the same
      name will <i>not</i> be called in the current implementation.  This
      module does not verify that the obj argument is a member of the
      package namespace.</li>
