For 'real' x3d h-anim animation you are using combinations of joint 
rotations and translations which animate the deformable skin. I think 
usually this would be created using timers and interpolators, or just 
send sets of rotations and translations created somewhere else 
directly to the joint node. Many old-style avatars are animated by 
directly moving sets of vertices that represent parts of the skin or 
outer surface. You can get an idea of the joint animation approach by 
reading the interpolators in the Skeleton Running scene from:
disable line wrap in simplist text editor.
