Axis specifications define the content and order of rows and columns that are placed along the vertical (row order) and horizontal (column order) axes, respectively. For this purpose, axis specifications can have any number of "Column/Row Specification" and "Loop Specification" as child elements.

A single form includes two sets of axis specifications, one for the vertical axis and one for the horizontal axis, but the content that can be configured is the same for both.

Axis specifications serve only as a place to put column/row specifications and loop specifications, so there are no items that need to be set for the axis specifications themselves.
