Hi Tony, I believe the fallback is not exactly emptyValue for a field's value - because if there is the field but it has no value - the TranscludeWidget will return empty. It is only if there is no field - that the fallback can be used. However, it appears it can be used by looking for the existence of a tiddler.
Cheers.
