/**
 * TParameterModule class
 *
 * TParameterModule enables loading application parameters from external
 * storage other than the application configuration.
 * To load parameters from an XML file, configure the module by setting
 * its {@link setParameterFile ParameterFile} property.
 * Note, the property only accepts a file path in namespace format with
 * file extension being '.xml'. The file format is as follows,  which is
 * similar to the parameter portion in an application configuration,
 * <code>
 * <parameters>
 *   <parameter id="param1" value="paramValue1" />
 *   <parameter id="param2" Property1="Value1" Property2="Value2" ... />
 * </parameters>
 * </code>
 *
 * In addition, any content enclosed within the module tag is also treated
 * as parameters, e.g.,
 * <code>
 * <module class="System.Util.TParameterModule">
 *   <parameter id="param1" value="paramValue1" />
 *   <parameter id="param2" Property1="Value1" Property2="Value2" ... />
 * </module>
 * </code>
 *
 * If a parameter is defined both in the external file and within the module
 * tag, the former takes precedence.
