- !ruby/struct:SM::Flow::P 
  body: This returns a hash of parameters. Each key in the hash is the name of the parameter in lower case and each value in the hash is the unquoted parameter value. If a parameter has no value, its value in the hash will be <tt>true</tt>.
- !ruby/struct:SM::Flow::P 
  body: If the field or parameter does not exist or it is malformed in a way that makes it impossible to parse, then the passed block is executed and its return value is returned. If no block is passed, the value of the <tt>default</tt> argument is returned.
