'''Important note:''' All functions in this section are ''updating functions'': they will not be immediately executed, but queued on the [[XQuery Update#Pending Update List|Pending Update List]], which will be processed after the actual query has been evaluated. This means that the order in which the functions are specified in the query usually does usually not reflect the order in which the code will be evaluated.
