From Unicorn Enterprises:
Unicorn XSLT processor lets you implement data transformations compliant to XSLT version 1.0. In addition, this tool supports extensions for report generation, text input, and ECMAScript (the ECMAScript interpreter is intergated). Communication between XSLT and ECMAScript engines is provided using XSLT object-based extensions.
This update improves performance and lowers memory consumption.
