Remarks
For any parameter, only one of isStringValueSupported, isDoubleValueSupported, isIntegerValueSupported, isElementIdValueSupported will return true. No attempt to convert between types is made. For example, calling GetStringValue, passing the identifier of a numeric-typed parameter will give an empty string. No exception will be thrown, and ParameterValueProvider will not attempt to convert the numeric value to a string.
If an element doesn’t have the requested parameter or the element’s parameter doesn’t have a valid value, ParameterValueProvider will attempt to get the parameter value from the element’s type - see GetTypeId..
