nux xom xml library
This is to announce the nux-1.0beta2 release (http://dsd.lbl.gov/nux/).

Nux is a small, straightforward, and surprisingly effective open-source 
extension of the  XOM XML library.

Features include:
	• 	Seamless W3C XQuery and XPath support for XOM, through Saxon.
	• 	Efficient and flexible pools and factories for XQueries, XSL 
Transforms, as well as Builders that validate against various schema 
languages, including W3C XML Schemas, DTDs, RELAX NG, Schematron, etc.
	• 	Serialization and deserialization of XOM XML documents to and from  
an efficient and compact custom binary XML data format (bnux format), 
without loss or change of any information.
	• 	For simple and complex continuous queries and/or transformations 
over very large or infinitely long XML input, a convenient streaming 
path filter API combines full XQuery support with straightforward 
filtering.
	• 	Glue for integration with JAXB and for queries over ill-formed HTML.
	• 	Well documented API. Ships in a jar file that weighs just 60 KB.

Changelog:

XOM serialization and deserialization performance is more than good 
enough for most purposes. However, for particularly stringent 
performance requirements this release adds "bnux", an option for 
lightning-fast binary XML serialization and deserialization. 
Contrasting bnux with XOM:

	• 	Serialization speedup: 2-7 (10-35 MB/s vs. 5 MB/s)
	• 	Deserialization speedup: 4-10 (20-50 MB/s vs. 5 MB/s)
	• 	XML data compression factor: 1.5 - 4
