Attribute to declare axes used in supplemental data binary tables. Although the order of the axes cannot be changed, some axes may be omitted. The axis names correspond to the axis integer identifiers as given in the "axisOrder" attribute of the "sdmDataHeader" element. Note that it is the set of *non-omitted* (i.e, present) axes that must be given.
