No problem.

Saving is simply done using the save method. There are various
overloaded variants of it available, the ones using a File or
OutputStream as argument will probably be the most useful for you.

Thus for example:

docXml.save(anOutputStream);

As a second argument, you can optionally provide an XmlOptions object,
which contains various settings to influence the saving. For example to
have nicely indented XML, you can do this:

XmlOptions options = new XmlOptions();
options.setSavePrettyPrint();
docXml.save(anOutputStream, options);

Not much opinion on this. Normally users can make these associations in
Windows. You could of course provide the possibility to configure apps
inside the detachment application. Since each install of the detachment
application is done on a specific operation system, I don't see a need
for 'different apps for different operation systems' though (unless you
were talking about having built-in defaults).
