No, it's not in the FAQ yet, I'll change that. 
Some other changes I propose: 

Explicitly mention that Fop 12 suports the older XSL working draft. I am not sure that this 
is necessary; has anybody seen a list of the changes and can comment on how Fop is 
affected by them?

**A new section on bugs:
Image support doesn't work in Fop 0.12.0 


**Limitations: 
font-family: you can only specify one font

Something else?

James: If somebody subscribes to fop-dev he or she probably receives an introductory 
message. Maybe it include a line like this: 
Please check the documentation at xml.apache.org/fop or the readme/status files 
coming with the source before you send bug reports to the group.
