Unfortunately, in my experience (see the numerical vs. textual id tag
thread), much energy is also wasted in trying to make the 2 projects
collaborate (the "JOSM standard" syndrome ;-) )

Because I don't know what capability the "presets.xml" format have. Is there
a doc somewhere?
Speaking of wasted efforts, trying to bend an existing format to my
requirements seemed much more wasted time than creating my own.
To whom would a common format benefit anyway (besides the translators, and
again translated tags is not one of my own requirements)?
My original idea is to allow users to create their own templates based upon
their own (local) requirements. A centralized, svn-based, common template
contradicts this idea.
It can be mitigated with, e.g., a wiki page with a repository of templates,
but does JOSM support changing templates on-the-fly or in preferences?
Obviously, using JOSM format is not a requirement for me. For easyness of
the translators using both editor (i.e. you AFAIK), I could use it, only if
I don't loose functionality.

Great. Why is there a dozen identical templates for the "higway" tag again,
Plus, my format supports references to <widget>, thus, for instance, the
"landuse" tag can be defined once and referenced in templates with
<widgetref> -> Maintenability enhanced.

Brussels is a bilingual city in a trilingual country (like others, I
suppose). The standard tagging for streets is to indicate the name in french
("name:fr"), the name in dutch ("name:nl") and both in the "name" tag, i.e.
"name:fr - name:nl". It's a great timesaver to just indicate the name:* and
have the "name" automatically generated.
