)

labelValuesVarBuilder & {} // input parameters expected

#name	string	Mandatory		The name of this variable.
#datasourceName	string	Mandatory		The name of the datasource to query.
#label	string	Mandatory	to name parameter	The label from which to retrieve the list of values. /!\ The filter library does NOT rely on this parameter to build the corresponding matcher, only #name is used.

#allowMultiple	boolean	Optional	false	Whether to allow multi-selection of values.
#capturingRegexp	string	Optional		Regexp used to catch and filter the results of the query. If empty, then nothing is filtered (equivalent of setting it to (.*)).

#display	Display	Optional		Display object to tune the display name, description and visibility (show/hide).
