Subject: [PATCH] webservice MDL-21510  added three defines for the description
 of ws optional value: VALUE_REQUIRED - if the parameter is not supplied,
 there is an error VALUE_OPTIONAL - if the parameter is not supplied, then the
 param has no value VALUE_DEFAULT - if the parameter is not supplied, then the
 default value is used (quick fix on default null value)
