nxslt 1.6.4 released

Another minor nxslt release is available - v1.6.4. This version adds support for the "extension-element-prefixes" attribute and fixes a glitch in transformation timings reporting.

What's the problem with "extension-element-prefixes" attribute? When using <exsl:document> extension element to produce multiple outputs some EXSLT-aware XSLT tools (like 4XSLT) rightly require "exsl" prefix to be registered in the "extension-element-prefixes" attribute. The problem was that .NET's XslTransform class while not supporting extension elements at all, throws an exception once encountering "extension-element-prefixes" attribute. So for running the same stylesheet with nxslt one had to remove "extension-element-prefixes" attribute, and with other tools - add it. Bad bad bad. So in nxslt 1.6.4 I fixed the issue by hiding "extension-element-prefixes" attribute from XslTransform class, so now you can use it in you stylesheets and enjoy better portability.

As a matter of interest, new .NET 2.0 XSLT processor - XslCompiledTransform class, while still not supporting extension elements, at least ignores "extension-element-prefixes" attribute. Good.
