Some others:

yguard     - http://www.yworks.com/en/products_yguard_about.htm
retroguard - http://www.retrologic.com/retroguard-main.html
jax        - http://www.alphaworks.ibm.com/tech/JAX
dasho      - http://www.preemptive.com/tools/

I am using yguard, there is an ant task available for it, so it is very
practical. Before yguard I used retroguard (yguard is based on this one)
and tested JAX. JAX _seemed_ the best, but it is/was not free (not sure
of its status now, it was years ago). I did not try dasho (not free).
