  What do you mean by "FI stax implementation for non-FI clients"?
The FI stax parser can only parse FI, so you must be using some other
parser if the input is XML.

  You may also want to take a look at Japex (https://
japex.dev.java.net) where you can find drivers in the JDSL (Japex
drivers standard library) and run performance tests for several of
the mainstream XML parsers --I don't think we have one for Woodstox,
but it should be easy to write by copying one of the others.
