calling order of sw/source/filter/ww8/attributeoutputbase callbacks

[Nicolas Boulenguez]

Hello.

In class sw/source/filter/ww8/docxattributeoutput.hxx or its parent
sw/source/filter/ww8/attributeoutputbase.hxx, the possible orders in
which the EndURL, RunText, EndRun (and probably StartURL) callbacks
may be executed when exporting an hyperlink is not explicit. This has
already caused at least four bugs: 47669, 52610, 53175 and 55820.

Docs.libreoffice.org only confirms what the names suggest:
* StartURL() and EndURL() are called in this order by
  SwWW8AttrIter::OutAttrWithRange() and
  MSWord_SdrAttrIter::OutEEField()
* RunText() and EndRun() are called in this order by
  MSWordExportBase::OutputTextNode.

Could someone tell me what can be asserted about the calling order, or
give me a link to some documentation?
