54 * each tag is an array of information about the

56 * * map_group - what group (used for precedence during conflicts)
57 * * mode - What type of item (self::MODE_SIMPLE usually, see above for all values)
58 * * 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' ).
59 * * choices - array of potential values (format of 'value' => true ). Only used with validateClosed
60 * * rangeLow and rangeHigh - alternative to choices for numeric ranges. Again for validateClosed only.

62 * * structPart - Indicates that this element can only appear as a member of a structure.
