Hi Abhideep. Thanks for reporting this bug. It's fixed in CVS. We were
building the 1.4.2 release at about the same time. So I'm not quite sure
whether this fix is in 1.4.2.
Cheers,

Subject: Validation Problems with
extension
07/19/2001
07:10 PM
Please respond
to
xerces-j-dev
I have defined a complexType called ShapeCollection which containes an
unbounded number of shapeElements of the type shapeType in the file
shape.xsd
shapeType is extended by type circleType defined in circle.xsd
The XML file with just one CircleType (shapeTest1.xml) validates fine. But
the XML file with with more than one CircleType fails validation. Am I
doing
something wrong or is this a bug with teh Parser.
Thanks a lot
Abhideep
