Sorry for jumping a bit late into this discussion. I just looked at the
issues with formatting-instruction, and it works nicely with the current
CVS version of openjade (as long as you declare it with 
declare-flow-object-class).

No, formatting-instruction is not listed in the extensions in
makeTeXFOTBuilder, since it is treated specially in 
Interpreter::installExtensionFlowObjectClass. I agree that this is 
confusing and should probably be handled differently.

I guess you are confusing SgmlFOTBuilder and TransformFOTBuilder here. 
SgmlFOTBuilder is the implementation of the fot backend, thus
there is no need for a formattingInstruction there. But the
TransformFOTBuilder which implements the sgml backend has it.
