+     *  Rules that return more than a single value must return an object
+     *  containing all the values.  Besides the properties defined in
+     *  RuleLabelScope.predefinedRulePropertiesScope there may be user-defined
+     *  return values.  This class simply defines the minimum properties that
+     *  are always defined and methods to access the others that might be
+     *  available depending on output option such as template and tree.
+     *  </summary>
+     *
+     *  <remarks>
+     *  Note text is not an actual property of the return value, it is computed
+     *  from start and stop using the input stream's toString() method.  I
+     *  could add a ctor to this so that we can pass in and store the input
+     *  stream, but I'm not sure we want to do that.  It would seem to be undefined
+     *  to get the .text property anyway if the rule matches tokens from multiple
+     *  input streams.
+     *
+     *  I do not use getters for fields of objects that are used simply to
+     *  group values such as this aggregate.  The getters/setters are there to
+     *  satisfy the superclass interface.
+     *  </remarks>
