I have also posted this to fop mailing list. It works in fop 0.20.5
only, because keep together is not implemented. In fop 0.92beta is is,
and so keep-together fails with the switch always. I have read the spec
of w3c and it is not clear what always means, it reads like the content
must stay together by all means. So, of course this fails if it cannot
be on a page and the exception is correct.

So it throws an exception. That means it cannot be generally used. A
keep together auto or <integer> should do it better. The default should
 have a property which always works and not fails, if a small blocks is
separated, the user can use something like the db:fo (?) function to
correct this.

Yes, I have completely redefined all keep-together properties.
