Michael Smith has released version 1.69 of the DocBook XSL stylesheets. These support transforms to HTML, XHTML, and XSL-FO. Major enhancements in this release include siupport for DocBook 5.0 (which uses a namespace, unlike previous version of DocBook) and localizations for Albanian, Amharic, Azerbaijani, Hindi, Irish Gaelic, Gujarati, Kannada, Mongolian, Oriya, Punjabi, Tagalog, Tamil, and Welsh. There are also many detailed updates to the formatting.
Oleg Tkachenko has released nxslt 1.6, a Windows command line utility for accessing the .Net XSLT engine. "New features include optionality for source XML or stylesheet, pretty printing, ASCII only escaped output and support for 'omit-xml-declaration' attribute of the exsl:document extension element." nxslt is written in C# and requires the .NET Framework version 1.0 to be installed.
Tkachenko has also posted the first beta of nxslt 2.0. "xslt 2.0 uses new XSLT 1.0 processor in the .NET 2.0 Framework - System.Xml.Xsl.XslCompiledTransform class. Hence it requires .NET 2.0 Beta2 or higher. As a first beta version, nxslt 2.0 Beta1 is quite limited - no support for XInclude, EXSLT, multiple outputs and embedded stylesheets yet."
