Template parameters is a new feature introduced in Elxis 2009.1. Using XML parameters you can easily change the layout and style of a template directly from within Elxis administration console and without touching the code. You can change colors, logo image, template layout, etc, just with some clicks. You will find at elxis wiki a detailed preserntation and developers guide for the template parameters. Note that the system is backwards compatible with prior Elxis versions.
