Creating a custom function set

You can create a custom function set with the following steps.

1. Create a custom filelist named filelist_customerExtensions.xml for the vendor extensions.
2. Create a functions definition file named customerExtensionsTree.xml in the installation_location/configuration/functions directory. The contents of customerExtensionsTree.xml are validated against the FuncTree.xsd file.
3. Create a function description file named customerExtensionsString_en.xml.
