Don't add styles in the output document when converting with the option --reference-doc

[me-kell]

Don't add any other styles in the output document other than the ones existing in the input document when converting with the option --reference-doc (and the extension +styles)

Currently when converting a DOCX-Document with the +styles extension and itself as --reference-doc with

pandoc input.docx -f docx+styles -t docx -o output.docx --reference-doc input.docx

following styles are added in the output document (which were not in the input document):

AlertTok , AnnotationTok , AttributeTok , BaseNTok , BuiltInTok , CharTok , CommentTok , CommentVarTok , ConstantTok , ControlFlowTok , DataTypeTok , DecValTok , DocumentationTok , ErrorTok , ExtensionTok , FloatTok , FunctionTok , ImportTok , InformationTok , KeywordTok , NormalTok , OperatorTok , OtherTok, PreprocessorTok , RegionMarkerTok , SourceCode , SpecialCharTok , SpecialStringTok , StringTok , VariableTok , VerbatimStringTok , WarningTok

The input.docx is an empty document created with a "clean" Normal.dotm.

Is there a way to disable the creation of those styles when the --reference-doc option is given?

Pandoc is also adding some settings in word/settings.xml not existing in the input document:

	<w:displayHorizontalDrawingGridEvery w:val="0"/>
	<w:displayVerticalDrawingGridEvery w:val="0"/>
	<w:doNotTrackMoves/>
	<w:drawingGridHorizontalSpacing w:val="360"/>
	<w:drawingGridVerticalSpacing w:val="360"/>
	<w:embedSystemFonts/>
	<w:footnotePr>
		<w:footnote w:id="0"/>
		<w:footnote w:id="-1"/>
	</w:footnotePr>
	<w:hyphenationZone w:val="425"/>
	<w:listSeparator w:val=";"/>
	<w:proofState w:grammar="clean" w:spelling="clean"/>
	<w:rsids/>
	<w:savePreviewPicture/>
	<w:stylePaneFormatFilter w:val="0004"/>

AFAICS Pandoc uses the files in data/doc.

When --reference-doc my_reference_doc.docx option is passed to pandoc, why not using the files in my_reference_doc.docx instead of those in data/doc?

We do carry over some things from the reference.docx. But if we just used everything, we'd get corrupt files (tried that; see e.g. #9522). So we use a conservative approach to guarantee that the docx we produced is not corrupt. It may be that we can be less conservative about some things. See also #7240.

Here is the code relevant to generating settings.xml:

The styles AlertTok , AnnotationTok , AttributeTok , BaseNTok , BuiltInTok , CharTok , CommentTok , CommentVarTok , ConstantTok , ControlFlowTok , DataTypeTok , DecValTok , DocumentationTok , ErrorTok , ExtensionTok , FloatTok , FunctionTok , ImportTok , InformationTok , KeywordTok , NormalTok , OperatorTok , OtherTok, PreprocessorTok , RegionMarkerTok , SourceCode , SpecialCharTok , SpecialStringTok , StringTok , VariableTok , VerbatimStringTok , WarningTok are for syntax highlighting. They are generated and depend on the highlighting style you specify. If you specify --no-highlight, they should not appear.
