Saving and importing Special Objects containing PythonScripts

Hi,
 
we created an Special Object with several strings and a PythonScript as
members.
The PythonScript takes a parameter in its parameter list (so that it can be
called like myScript("myparameter") )
We were used to the fact, that parameters get lost when im-/exported as XML,
in former versions of ZMS.
 
But in version 2.10.4-13 (see details below) the parameterlist gets even
deleted any time the Special Objects is saved in the ZMI.
We do not edit the PythonScripts via the ZMS interface but with the help of
alternative editors.
 
To improve the way of developing SpecObjs and to make them portable we want
to make the following feature request:
- please keep the parameter list when a SpecObj gets saved
- please include this list in the XML im- and export
 
Thank you!
 
Best Joern
