This is the intended behavior and strategy for publishing an array of
elements. Because it can be hard to tell when a group of elements
represents an array vs. a list of independent values, Muse requires arrays
to be wrapped in a parent/"array" element. The publish(QName, Element[])
method is applying the QName to each value (Element) in the array and
adding a wrapper element. To publish an array of values that are distinct,
you need to wrap them in an element yourself and call publish(QName,
Element).
