<Multidimensional_data>

ELEMENT

<name>

REQUIRED

<pds:local_identifier>

OPTIONAL

<description>

OPTIONAL

<Primary_Value>

REQUIRED

Main data array

<pds:Local_Internal_Reference>

REQUIRED

<Axis_Value>

OPTIONAL, REPEATABLE

Data object associated with a specific axis of the main data array

<pds:Local_Internal_Reference>

REQUIRED

<primary_axis_number>

REQUIRED

"index" of corresponding axis. Starts at 1. Not clear if this is supposed to be sequence_number, but presumably is.


<Face_Value>

OPTIONAL, REPEATABLE

Data object associated with "two or more axes" of primary data object.

<pds:Local_Internal_Reference>

REQUIRED

<Face_Axis>

REQUIRED x2, REPEATABLE TO x16

Identifies one axis of "face" set

<primary_axis_number>

REQUIRED

Axis in primary data array

<face_axis_number>

REQUIRED

Index of axis in "face" array.

<Aligned_Value>

OPTIONAL, REPEATABLE

I think this means a data object with intentional the same structure as the primary array, so the corresponding values match up in index space. There is a requirement stated by not enforced for the structures to have "the same dimensions". Not clear how this could be enforced

<pds:Local_Internal_Reference>

REQUIRED
