The xBus supports value mappings. The intention of this feature is to map key values from one system to corresponding values in another system. This is an important feature to allow connecting systems without changing their interfaces.

The syntax of the mapping table is just the standard syntax for configuration entries. The chapter in the configuration entry is always "Mapping", the section the name of the concrete mapping and the key the source value. Attached is the destination value.

An example of a mapping configuration looks like this:

chapter	section	key	value
Mapping	Boolean2YN	true	Y
	Boolean2YN	false	N

Within XML transformations and record type transformations such value mappings are executed by XBUS_Stylets, included in the XSLT stylesheets.
