"SHALL" means exactly the same thing as "MUST", per RFC 2119.  It's "SHOULD" and "MAY" that you should be worried about. ;-)<BR>

<BR>
Hi all!<BR>
<BR>
I just had a chat with a colleague and he said:<BR>
<BR>
- you know Sascha, I hate to read 'shall' in specifications. I then never know if a product supports it<BR>
<BR>
So my question is: what is the reason for using "shall" instead of "must"?<BR>
<BR>
Thanks,<BR>
Sascha<BR>
