+ Assumptions:
+
+ The attribute currentValue will throw an exception
+ if it cannot be set i.e. if the value is not a
+ member of the interval.
+ This may not be the 'desired' behaviour given gObject
+ equivalent. Thus it could be changed to be:
+
+ readonly attribute double currentValue;
+ boolean setCurrentValue (double long value);
+
+ GValue can represent many basic types.
+ Since this interface is designed to represent
+ an interval and a member of double should
+ cover the cases of char int and float.
