The map operator returns an :array, and XML output requires only objects. The {( ... )} syntax converts an array of objects to an object that contains each key value pair (tuple) contained in those objects.

To get past the error you see in the editor, try putting the whole expression within the {( )} nested braces, and see what you get afterward.

Remember that to produce XML, you must output only objects, and that those objects can have more than one key/value pair with the same key. This corresponds to XML nodes. While debugging, it's often handly to change your output to java, and see what you're working with, like so:

%output application/java
