OPEN XML add custom not visible data to paragraph/table

Question

Is there a way to store additional data for a paragraph, that would be persisted after user opens and saves a document in MS Word.

Ive been using CusotmXML for this, but it turns out that this is no logner possible due to the fact that MS-Word strips all CusotmXML elements from the document structure.

Every single paragraph or a table has an ID that I would like to "pair back" to my data-source. So later when I read the docx again I can identify origins of every unchanged paragraph/table in the document.

A possibility would be to insert a SET field. This creates a bookmark in the document to which you can assign information. There's no way to protect it from the user removing it, however. A DATA field might also be a possibility.

Unlike "vanish" (which I believe is equivalent to "hidden" font format) the information would not display if the user is in the habit of displaying non-printing information. It will display, however, if the user toggles on field codes (Alt+F9).
