This element replaces the location/coordinates/@precision attribute. "Supporting-information" is not perhaps the best name for this, so suggestions are welcome, but "precision" is, in this case, misleading.
- location/supporting-information/@code - A code from the IATI Geographic Supporting-Information code list. 1 = Exact, 2 = Approximate
- location/supporting-information/text() - The description of the supporting-information code
- location/supporting-information/ @xml:lang - The language of the description. [Only if different from default language.]
