Local fix

• A workaround consists in wrapping the array of complex type
  elements into its own XML type, and redefining the ruleset as an
  instance of this wrapper type, instead of having it as an array
  of the wrapped type.
  

Problem summary

• Array of XML objects are not supported as parameters. It is not
  possible to create one with Rule Designer any longer. The code
  of the HTDS does not handle the fact that ruleset generated
  earlier can still be used.
  A change in the code of the HTDS is introduced to handle
  graciously this use case.
  

Problem conclusion

Temporary fix

• For existing ruleset refactor the parameters by creating a new
  root element including the array of XML objects as an attribute.
