ChangeMan ZMF 5.3.x (available since 2003) was the first release delivered with a very rich set of functions that allows you to perform many (though not all) tasks in ChangeMan ZMF without using ChangeMan ZMF's ISPF client (to communicate with the ChangeMan ZMF server, aka the CMN started task). This set of functions is commonly referred to as "ChangeMan ZMF's XML services" (for short: the "XML services").
