I have a maxLength facet on a complexType with simpleContent that extends a
base complexType. Schema validation performed by the included program with the
included schemas & xml file results in the stack trace listed below. Note the
message refers to the relevant anonymous type as [type 'null'] which is not
helpful. In this case, a more helpful error message would refer to either the
complexType name itself or its base type name. Should I open a JIRA for this
issue?
STACK TRACE:
org.xml.sax.SAXParseException: cvc-maxLength-valid: Value '
commentZZZZZZZZZZZZZZZZZZ
' with length = '30' is not facet-valid with respect to maxLength '20' for
type 'null'.
