 | | | Cannot validate restricted complex type in schema | Cannot validate restricted complex type in schema 2004-02-10 - By Kornél Esti
Hi all,
I'm having a problem with restricted complex types using Xerces-J 2.6.1.
I have tried to validate the complex type restriction example from the
Schema primer:
http://www.w3.org/TR/2001/REC-xmlschema-0-20010502/#DerivByRestrict
using the supplied sample xni.XMLGrammarBuilder.
Running `java xni.XMLGrammarBuilder -f -a ipo_test.xsd`
gives me:
[Error] ipo_test.xsd:56:37: rcase-NameAndTypeOK.7: The type of element
'item', 'null', is not derived from the type of the base element, 'null'.
[Error] ipo_test.xsd:56:37: derivation-ok-restriction.5.4.2: Error for type
'ConfirmedItems'. The particle of the type is not a valid restriction of
the particle of the base.
See the files used below.
Am I doing something wrong?
Greetings,
Kornel
