Java library implementing the Fast Infoset standard

 Fast Infoset specifies a standardized binary encoding for the XML Information
 Set. An XML infoset (such as a DOM tree, StAX events or SAX events in
 programmatic representations) may be serialized to an XML 1.x document or, as
 specified by the Fast Infoset standard, may be serialized to a fast infoset
 document.
 .
 Fast infoset documents are generally smaller in size and faster to
 parse and serialize than equivalent XML documents.
