Thanks for your support concerning my problems.
Could anyone also please comment on the exception I
described that occurs when I try to unmarshal my XML
document.
Here it is again.
This is the relevant mapping file part:

> cst:depends="log.Systemstates" cst:identity="id"
> cst:key-generator="MAX">

I try to unmarshal an XML document that contains this:
> <state state-moment="StateBegin"
> stamptime="2005-10-25T11:46:09" >INIT</state>
This exception occurs:

I cannot see a reason why the string "INIT" should not
be allowed at this location.
