The infoset is not a format at all. It is a data model, one of many. 
This data model is based on text, not binary data.

This data model is related to but not identical to real XML. There are 
*many* infosets that cannot be expressed in well-formed XML (an infinite 
number in fact). There are also well-formed and even namespace 
well-formed XML documents that do not have infosets. Off the top of my 
head, I *think* that all namespace well-formed XML documents that only 
use absolute namespace URIs have well-defined infosets. However, I could 
be forgetting a tricky corner case.
