Dear TC members, here are some test documents. StyleEmptyNoListInherit contains headings, all with text:outline-level="1". The used paragraph styles have style:list-style-name="myNumbering" or style:list-style-name="" or no such attribute, but the parent style has style:list-style-name="myNumbering" HeadingWithoutList contains headings, with different text:outline-level values. The used paragraph styles are different, but all have style:list-style-name="myNumbering" The files with _text_number have the element <text:number> in the headings, as mentioned in the last call. The value is a string with the expected numbering, enclosed with to make it different from real numbering. My observation is: LibreOffice, TextMaker, ONLYOFFICE and WebODF do not show numbers and ignore the <text:number> element. Word 2010 (after "repair") shows some numbers and shows the content of the <text:number> element. But I see no logic in the way it is down. But perhaps Aarti gets some information from the Word team.
