title: When writing a new SOAP web service why would I choose to use version 1.2 over 1.1?
body: <p>The numerous technologies for writing SOAP web services allow me to create services which adhere to either SOAP 1.1 or 1.2. It's not clear to me what benefits 1.2 provides over and above 1.1. This leads me to the conclusion that I should always use 1.1 to accommodate the largest number of compatible clients.</p>
  
  <p>Why would I choose to create a SOAP 1.2 rather than a SOAP 1.1 web service?</p>
