[josm-dev] Can I style by user in mappaint?

[Ævar Arnfjörð Bjarmason]

I wrote my first style today which is already available in JOSM, the
style system is very nice:

    http://github.com/avar/osmis-josm-style/blob/master/elemstyles_is.xml

It's for an import I'll be doing in Iceland, due to how the import is
being done I'd like to have a special rule that applies in my style if
the element was last edited by a given user (like user:foo in the
search engine). I can't find this in the docs or the xml comments for
mappaint.

Is it possible to write a rule like that?
