There exists a field "Slide Title" (Impress) or "Page Title" (Draw), which is written to file as element loext:page-name. This is related to bug 88056 and bug 47302. The description in https://wiki.documentfoundation.org/Development/ODF_Implementer_Notes/List_of_LibreOffice_ODF_Extensions is missing. I have already added a new row, but content should be added by developers of that feature.
The row "loext:page-name" in the web page https://wiki.documentfoundation.org/Development/ODF_Implementer_Notes/List_of_LibreOffice_ODF_Extensions exists. But these is no content in cases OASIS cross-reference, Standardized in ODF and Standardized as ... Is it normal?
I had added the row with content I know, but "Functional Area" needs review by the developer. It seems there is no proposal yet for ODF, so it is correct that the fields are empty.
So, perhaps may we close this bug?
