I believe[*] it is possible to define a new element type that describes
an abstract ExecutableApplication element with these generic bits in and
which is grandfathered into being a supertype of the POSIXApplication
element (as well as being the parent of the WindowsApplication you're
positing). This would require a small change to the existing schema,
though we'd want to make sure that the documents accepted by the schema
remained the same, and would enable this suggestion (which I approve of,
by the way) to be slotted into the larger scheme of things without fuss.

By the way, what would these extra Windows-specific bits be? I can
imagine a number of the POSIX things being dropped (e.g. the limits) but
I'm not nearly well-versed enough on Win (despite using it a lot) to be
able to think what these extra additions might be. Just out of
curiosity! :-)
