There isn't one.  XMI is a difficult standard to follow and we don't do it
very well.  I'd be curious to know how well Rational or Together or the
like do it.

The latest version of XMI is 1.2 I think but it's DTD does seem to say
version 1.1 which is strange, but probably our bug.

The 1.3 is the version of UML.  It could be upped to 1.4 if you wish.

There are probably numberous places where the file format could be updated
to be more XMI compliant which would be great (so long as we retained the
possibility to load Umbrello 1.1 files).
