actually it used to be the case that the one in sax is a copy paste of
the SvXMLUnitconverter, but i cleaned that up a couple of months ago.
now the remainder of SvXMLUnitconverter is stuff that cannot be moved to
sax module as-is, because it depends on e.g. the tools horror, or it
uses members of SvXMLUnitConverter; don't know which applies to the
double/datetime conversion.

hmm... even ODF 1.0 referred to XMLSchema;
i've taken a quick look at the OOoXML format:

but that doesn't seem to mention where the datatypes are from...

perhaps we don't import anything with ISO8601 dates?
(i'm assuming that OOXML has its own date format re-invented from
scratch, like everything else and with special support for 1900-02-29 :)
