Confidential data can be in any form. And eavesdroppers would not 
neglect MTOM attachments. For example an image taken by a security 
camera that need to be transfered to the Central Investigation Unit as 
an MTOM attachment. ;) Just to name one. Also anything in the binary 
form. A secret key for example.
So we need to make sure that its not visible in the wire content. That's 
why we need to encrypt.
