what SOAP offers which xml based dmtf cim does not ??

["Awasthi, Anand" <An...@bmc.com>]

 hi all

actually i am newbie who has just started working on SOAP.
i am wondering whether SOAP was actaully need or not bcoz we already had 
DMTF cim which could be used for xchanges of information.
the only reason which i see for evolution of SOAP was that dmtf cim only
desribes and changes management information and that may be the limitation
and 
thats why SOAP came into markter ?? am i correct ?? but is this the only
reson for 
SOAP's entrance as messgage transfer protocol ??


could you pls  clear my doubts i will be vey thankful to you. or pls direct
me to 
the correcot pointers.


Thanks
