Check a couple more things before you give up.
To use any extension functions the parameter
'use.extensions' needs to be non-zero (the default is zero).
To use the callouts, the 'callouts.extension' parameter
needs to be non-zero (that's 1 by default).
And the parameter 'callout.graphics.path' needs to
be set to the directory containing the callout image files.

Then you need to make sure the correct extensions jar file
is in your CLASSPATH when you run Xalan.  You need
docbook-xsl-1.48/extensions/xalan2.jar in your case.

Those steps should at least get the callouts code into
the fo file.  Whether FOP will handle it properly
is another question.
