Reads the instance document specified by the input of the map into a map element.
This function is used as the I/O expression of the element to contain the data to be read. The contents of the source URL for the map are read during the map execution populating the values of the element containing the I/O expression and any subordinate elements.
You may not nest the use of this function. In other words, if a map element contains an I/O expression, no subordinate map element may contain an I/O expression.
This function can only be used in the IO/Database tab.
