[ANN] Saxon 8.1

Just a quick note to let everyone know that Saxon 8.1 is available:

http://saxon.sf.net/          (open source version)
http://www.saxonica.com/      (commercial version)

There are large numbers of changes but most of them taken individually are
minor.

The commercial licensing has been made more flexible, in particular there is
a reduced price if you want XSLT or XQuery but not both. 

There are now added goodies in Saxon-SA beyond schema-awareness, most
notably an extension to support higher-order functions. This has been used
on the XQuery side to provide access to facilities equivalent to XSLT's
for-each-group and analyze-string.

This release was developed in collaboration with Stylus Studio, and includes
features designed to enable improved debugging and diagnostics when Saxon is
used from within Stylus Studio.
