GDML Rotation more than one axis

Okay I understand Rotation when it is defined with one axis
i.e.`<rotation name=“RotateZ” z==“30” unit=“deg”/>

But what if more than one axis is specified?

If one is rotating by more than one axis, would not also the order affect the final rotation.

If more than one axis is specified in the same statement, the order applied is first X, then Y, then Z.
