ReadURL
Reads the contents of a URL 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 URL will be read during the map execution populating the values of the element containing the I/O expression and any subordinate elements.
You may use this function in multiple map elements in order to read multiple files. You may not however 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 be used to allow reading from multiple documents/objects in the map execution that are assigned dynamically by calling methods on the MapExecutionContext. In this case the URL is not required.
This function can only be used in the IO/Database tab.
