    <!-- simple echo -->
  <echo>
    #{'${guid}'.toupper}
   </echo>

    <!-- create new property for further processing -->
    <fl:let>
     guidtoupper := '#{'${guid}'.toupper}'
    </fl:let>

    <echo> $${guid} before => ${guid}</echo>

    <!-- overwrite existing property -->
  <fl:let>
   guid ::= '#{'${guid}'.toupper}'
  </fl:let>

    <echo> $${guid} after => ${guid}</echo>
