What you did is pretty intuitive, however there is a misunderstanding:
``the choice element will execute the first alternative which can be
executed''
should read:
``the choice element will execute the first alternative which, given the
editing context, makes it possible attempting its execution''
And, of course, there is nothing on Linux which could prevent XXE from
attempting to execute
/bin/sh -c 'c:\windows\system32\notepad.exe "foo.xml"'
In the absence of a higher-level facility in XXE, you need to rewrite
the macro like this:
---
<command name="editXMLSource">
<macro>
<sequence>
<command name="XXE.save" parameter="[ifNeeded]" />
<choice>
<sequence>
<test
expression="system-property('path.separator') = ';'" />
<command name="run"
parameter='c:\windows\system32\notepad.exe "%D"' />
</sequence>
<command name="run" parameter='emacs "%D"' />
</choice>
<command name="XXE.open" parameter="[reopenIfNewer]" />
</sequence>
</macro>
</command>
---
Note that system-property() is only available in XXE V3.0 Patch 1. See

PS: Simpler, install GNU Emacs on Windows
(http://www.gnu.org/software/emacs/windows/ntemacs.html).
Works great ;-)
