34 * * map_group - what group (used for precedence during conflicts)
35 * * mode - What type of item (self::MODE_SIMPLE usually, see above for all values)
36 * * validate - method to validate input. Could also post-process the input. A string value is assumed to be a static method of XMPValidate. Can also take a array( 'className', 'methodName' ).
37 * * choices - array of potential values (format of 'value' => true ). Only used with validateClosed
38 * * rangeLow and rangeHigh - alternative to choices for numeric ranges. Again for validateClosed only.
39 * * children - for MODE_STRUCT items, allowed children.
40 * * structPart - Indicates that this element can only appear as a member of a structure.

42 * currently this just has a bunch of exif values as this class is only half-done
