More of an FYI for others rather than an issue, but if you include an SVG in your fo FOP will try to render it using Apache Batik which in turn uses AWT which is not implemented by IKVM. The error I got wasn't super helpful but if you see anything in the stack trace related to AWT, basically, it's not going to work:
Here's the exception I'm seeing in my particular scenario:
System.TypeInitializationException: The type initializer for 'org.apache.batik.bridge.DefaultFontFamilyResolver' threw an exception.
