Well, sequences, actually. Tuples don't exist in the data model, though they
are used internally to describe the semantics of "order by".

It actually needs a comma:
define function my_func() as element()*
<bar>Some More Text</bar>
Element constructors can be adjacent when they are part of the content of
another element constructor, but not when they are freestanding expressions.
Confusing, but you get used to it.
