FYI other options include:
- modifying your %JAVA_HOME%/lib/jaxp.properties file (or creating  
one if it doesn't exist)
- supplying the property via java's '-D' command-line option

jaxp.properties would look something like:

(analogous for 'java -D...')

The first one has the advantage that it is completely independent of  
our FOP shell scripts, but it affects all Java Apps, so is really  
only useful when the user wants to use Saxon everywhere instead of  
Xalan (the default).

The second one would still require a modification to the shell  
script, maybe in the form of an optional parameter you can pass to  
the script. If the parameter is present, the java command-line at the  
bottom of the script can be made to take into account the override  
for that particular system property. (So, this could turn out to be  
beneficial in other areas as well, where the user needs to override  
sysprops... Could this solve the issue of using catalogs?)

How about allowing:

fop -sysprop ... -fo ... -pdf ...

The -sysprop switch is caught by the shell script, and incorporated  
into the java command-line.
(Using '-D' here would create confusion with FOP's own '-d' switch,  
unless we were to allow only the slightly more verbose '-debug')

Just a thought.
