The following paragraph 2.4.1. mentions that union types are the union of "one
or more other datatypes":

http://www.w3.org/TR/xmlschema11-2/#atomic-vs-list

While the definition of such types allow for "zero or more" (which allows
"user-defining" xs:error):

http://www.w3.org/TR/xmlschema11-2/#union-datatypes

Did I just miss something, or could it be a typo in paragraph 2.4.1.?
