Reusing XML/XSLT editors possible?

Hello!

I'd want to add an additional (project specific) panel to the XML editor
or - better - to the XSLT multiview editor. E.g., from an additional action
for the XML node, I'd like to do sth. like
"getLookup(XSLTDataObject).getMultiViewEditor().addView(myView)". Is there
any api for doing this?

If not, is it possible to do reuse the XMLEditor in a MultiView object? Or
is the editor implementation probably to heavyweight, i.e. related to
probably suspicious TopComponent handling?

Kind regards
