odf 1.1 4.1.1

If a heading has a numbering applied, the text of the formatted number
can be included in a <text:number> element. This text can be used by
applications that do not support numbering of headings, but it will be
ignored by applications that support numbering.

Perhaps 'the text to be used instead of an automatically generated
number'  can be included .... might be clearer?


 No  definition of 'has a numbering applied' is available .


Should
<text:h
    text:is-list-header="false"
>Heading</text:h>
be used for this purpose? Unclear if there is any semantic
interpretation of this value for this attribute.

How can it be determined programmatically that an application 'does
not support numbering of headings'?
Untestable paragraph or implementation dependent?
