45 * each tag is an array of information about the
46 * tag, including:
47 * * map_group - What group (used for precedence during conflicts).
48 * * mode - What type of item (self::MODE_SIMPLE usually, see above for
49 * all values).
50 * * validate - Method to validate input. Could also post-process the
51 * input. A string value is assumed to be a method of
52 * XMPValidate. Can also take a array( 'className', 'methodName' ).
53 * * choices - Array of potential values (format of 'value' => true ).
54 * Only used with validateClosed.
55 * * rangeLow and rangeHigh - Alternative to choices for numeric ranges.
56 * Again for validateClosed only.
57 * * children - For MODE_STRUCT items, allowed children.
58 * * structPart - Indicates that this element can only appear as a member
59 * of a structure.
60 *
61 * Currently this just has a bunch of EXIF values as this class is only half-done.
