Yes, let me copy the dev list.

The new <text:line-break loext:clear="..."> attribute I added is to
represent a clearing break. This is something HTML and DOCX has, so we
had formatting loss when importing those formats, this extension is
meant to fix this problem.

OOXML documents the various types of a clearing break at 17.18.3
ST_BrClear (Line Break Text Wrapping Restart Location), so far Writer
layout just handles "all" and "none", the work is still in progress.

HTML has <br clear="..."> for the same.

sw/qa/extras/ooxmlexport/data/clearing-break.docx is a sample document:
we used to incorrectly render this document without clearing breaks.

Does that help?

Thanks,

Miklos
