* - lookup: An array of objects, one for each option, which contain name and

|
* value properties. lookup can be a function which returns this array
|
|
* - data: An array of strings - alternative to 'lookup' where the valid values
|
|
* are strings. i.e. there is no mapping between what is typed and the value
|
|
* that is used by the program
|
|
* - stringifyProperty: Conversion from value to string is generally a process
|
|
* of looking through all the valid options for a matching value, and using
|
|
* the associated name. However the name maybe available directly from the
|
|
* value using a property lookup. Setting 'stringifyProperty' allows
|
|
* SelectionType to take this shortcut.
|
|
* - cacheable : If lookup is a function, then we normally assume that
|
|
* the values fetched can change. Setting 'cacheable' enables internal
|
|
* caching.
