OR operator uses exceptions for control flow #146

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
The OR operator uses exceptions for control flow.

If you have a lot of occurrences of the OR pattern with leaf-node XSD types, 
the exceptions get expensive:

  empty | xsd:integer

Even if you have empty first, it still tries to parse the content as 
xsd:integer, and gets an exception thrown back up to the disjunction.
