SAX Infoset Mapping

Hi,

the DOM WG has kindly produced a fairly useful document (if you're into 
that sort of thing) that describes the mapping between the DOM's model 
and the Infoset:

   http://www.w3.org/TR/DOM-Level-3-Core/infoset-mapping.html

I've been looking around for a similar document mapping SAX and the 
Infoset, but so far to no avail. Does anyone here know of one? Would be 
interested to write one?
