Data items in the DIFFRN_DETECTOR_ELEMENT category record
the details about spatial layout and other characteristics
of each element of a detector which may have multiple elements.
In most cases, giving more detailed information
in ARRAY_STRUCTURE_LIST and ARRAY_STRUCTURE_LIST_AXIS
is preferable to simply providing the centre of the
detector element.
