I am working for Motorola not for a long time anymore and if you're 
interested, I can find some information and some contacts who could help you 
and tell you if "there is any hope to bring it to compliance".
The official documentation is available on the internet (public access):
http://e-www.motorola.com/webapp/sps/library/docu_lib.jsp

I also have a contact name but perhaps I could find someone more relevant 
for this problem.
here is his address : Simon.Walker at motorola.com

Don't hesitate to give more details on what you need to know
Hope it will help

Xavier
