That makes sense. It explains the unusual attributes and elements.

I have only got Word2010 and Word365. They have nothing in the UI to 
generate a lockedCanvas, and I find only API explanations on Microsoft

Thank you. If I open that in Word365 and resave it with "keep 
compatibility" enabled, it keeps the lockedCanvas. It is not possible to 
edit the content, but changing the anchor type is possible. That is 
sufficient for my upcoming unit test.

Kind regards
