Hi Pedros,

The /docs/runtime.html#stax document in the 1.1 distribution gives 
information about using StAX rather than XMLPull. This doesn't cover how 
to work with an existing XMLStreamReader, though.

I just realized in looking through the JavaDocs that a key class for 
this was unintentionally made package access only. This is the 
org.jibx.runtime.impl.StAXReaderWrapper class (doesn't show in the 
JavaDocs since these are only the public classes). You can easily change 
the source code for this class (under /build/src) to make it public 
access, then recompile with "ant current" in the /build directory. To 
use this class, you currently need to work with the implementation 
classes rather than the runtime interfaces - so once you've created an 
IUnmarshallingContext cast it to 
org.jibx.runtime.impl.UnmarshallingContext, then create a 
StAXReaderWrapper class wrapping your existing XMLStreamReader and set 
it on the UnmarshallingContext with the setDocument() call. You can then 
use the UnmarshallingContext unmarshalElement() call to unmarshal the 
bound element from the XMLStreamReader.

I'll try to get out a beta 2 release of the 1.1 code soon which will 
have the corrected StAXReaderWrapper class, along with other fixes.
