Hello,
in my opinion this syntax is more readable: 


  | 
  |        <decision name="Collateral" expression='#{ collateral == "true" ? "true" : "false" }'>
  | 		<transition to="fork1" name="true"></transition>
  | 		<transition to="NO_COLLATERAL" name="false"></transition>
  | 	</decision>
  | 
  | 

The expression-based decisions must return a transition name.
