Hello Armin,
you could give following store parameters a try:
true
false
If the xhtml schema would not exist in Tamino, the content would be stored in the nonXML area. This should solve your requirements.
Please note, that text documents are de-/en-coded by Tamino, even, if stored in the nonXML area.
Best regards
juergen
