Why do you need a single rotation? If you just need a single value to 
pass around, do something like this:

#declare Rotations = transform {rotate <a,b,c> rotate <x,y,z>}

object {MyObject
    transform Rotations
}

If you're after a way to transform vectors, make sure you include 
transforms.inc and use "vtransform(Point, Rotations)".
