You might want to check out the XSD and WSDL editor code to see how they 
do it, as well as the code from the XMLMultiPage Editor.  I believe you 
have to tell the StructuredDocument who is listening for it's events.

Konstantin: if you just want a pretty formatted document, you could 
programmatically have it execut the SSE formatter to format the document.

Again the best examples are probably the existing XML, XSD, and WSDL 
editors.
