Styles do not apply to Sections. They can be applied to Tables, Paragraphs and Characters only.

When you apply formatting restrictions, only the approved Styles can be used. Hard-formatting and Style changes are not allowed. Of course, you can't force a user to use a given Style appropriately, but that's a different issue.



I don't understand your contention re Section breaks and document structure, which should in any event be defined via the proper use of Styles.

Thanks Paul, that’s very helpful. If you're confirming that document structure should be defined via the proper use of Styles, then what I need to achieve additionally is:

1. Password Protect the document enabling track changes
2. Only allow 3rd party to modify normal/body text in the document, but not change headings (ie. certain styles) as this will modify the document structure.

Is that possible? I tried removing the heading styles from the list under 'Limit formatting to a selection of styles', however this completely removed the style from the underlying document which is not what I wanted to achieve.
