Many XPage controls have properties which have a finite number of possible values. When the control is being defined a property editor may be defined to set the value of the property in Domino Designer (in the all properties view). The editor may be parameterized, whereby the parameters are a list of legal values for the property. This new code examines each property definition for the existence of such parameters. If the parameters exist they are appended to the documentation for the property as a list of 'legal values' for the property.
