Discussion about highlighting (MS compatibility issue)

[V Stuart Foote]

Zolnai, *

Did not realize there were actually two OOXML/MSO attributes that had to be
manipulated to handle highlighting in MS Office formats.  And that we'd been
fudging it with just one--your patch with just one
attribute--RES_CHRATR_HIGHLIGHT manipulated as background fill in LO.  

This recently came up in a new twist, over how we've been handled it--since
your work 2013-09--needing to turn highlighting on or off by selection and
removing direct formatting background fill.  (tdf#88990).  That has been a
bit cumbersome but works to clear the direct formatting in an imported
docx/doc document that either shading or highlighting receives as an ODF
document.

Should we care about this from an ODF 1.2  standards  perspective?  Since we
apply direct formatting to give background fill "highlighting" to ODF
documents--is there any way in ODF to differentiate  formatting that is
"highlighting" vs. what is "background fill"?    I don't know...  anyone?

If there is a specification for it in ODF ,  then certainly creating an .uno
action and GUI button to apply a "highlighting" style, or direct formatting
of text, would be correct.  But if we are just pursuing this for
"interoperability" seems like we are chasing our tails over it.

If  there is not, then why should we care that OOXML/MSO and ODF diverge on
this handling?  Seems like in that case, we should continue to make do with
only background fill mapping of DOCX/MSO highlighting on import. And on
export we don't differentiate--it  all remains background fill in the
DOCX/MSO formats.

Key is what ODF 1.2 supports, or maybe what is proposed in 1.3 that might
also be implemented.
