When I read the Last Call Working Draft [1] of the Web Services Addressing 
1.0 - Core specification, I see that the cardinality indicator associated 
with the "[destination]" property in section 3. Message Addressing 
Properties [2] is "(mandatory)".  Unfortunately, I do not see a definition 
of "(mandatory)" anywhere in the same document (I even checked RFC 2119 
[3]).  So, while I would doubt that anyone would argue about associating 
minOccurs=1 to the term, it is less clear what value of maxOccurs to 
associate.  I can see arguments for both one and unbounded.  So...

(1) What did the authors intend for the meaning of "(mandatory)"?

(2) If the intent was in fact maxOccurs=unbounded, could you help me to 
understand the use cases behind the intent?  I have some ideas, but I am 
sure that the authors must have more.
