Below is a list of all possible parameter file xml elements. For each element an example is provided as well as information about the element's host element, the element's type and the element's content. Note that all words(element names, key string words, key string variables) in bold are hard-coded, all in italic are user-defined (this does not apply to the example box). The spelling of hard-coded words must be abide by, the spelling of user-defined words is user-defined.
