      public WbQuantityExpr(WbExpression<? extends org.wikidata.wdtk.datamodel.interfaces.StringValue> amountExpr, WbExpression<? extends org.wikidata.wdtk.datamodel.interfaces.ItemIdValue> unitExpr)
      Creates an expression for a quantity, which contains two sub-expressions: one for the amount (a string with a particular format) and one for the unit, which is optional. Setting unitExpr to null will give quantities without units. Setting it to a non-null value will make the unit mandatory: if the unit expression fails to evaluate, the whole quantity expression will fail too.
