Language dependent html.stw files live in extras/source/templates/wizard/desktop/lang/<language>/
(1) Why are they in old OpenOffice.org XML format, and not in OpenDocument?
(2) html.stw files are identical in en-US, de, es, eu, fr, hu, it, km, sv, vi. Maybe the differences in other languages are not important? Would it be possible to create a language independent html template that fits all? We could save some bytes in the install sets.
Code for this lives in sw/source/filter/html/swhtml.cxx, HTMLReader::GetTemplateName()
Language independent html.oth should be installed into share/template/common/.
