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.
