(snip) I forgot to mention: you must do this before the document is saved, e.g. in a listener callback that waits for the document events "OnSave", "OnSaveAs" and "OnCopyTo". But you also can do this at any other time before the user asks for saving, the document will then appear as modified. The inserted content is part of the document storage then (and is accessible for reading via storage API), but it will not appear in the file until the root storage is committed. But in our framework only the document itself is allowed to do this. This usually happens when the user asks to save the document.
