Description Ghislain Fourny 2013-02-04 14:28:59 UTC 
The following paragraph 2.4.1. mentions that union types are the union of "one or more other datatypes":

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.?
