This doesn't have to be an inherent limitation of SMIL syntax.  Back in 
2004, I proposed a way to reuse declarative animations:

SVG already has an architecture geared toward reuse of resources, from 
paint servers (like gradients) to graphics features (like filters, 
clipping paths, masks, and so on) to graphics themselves (like <use>, 
markers, etc.).  Reusing animations seems very natural to me.
