[Bug xml/31819] New: XML that is invalid according to schema parses successfully

[fullung at gmail dot com]

Test case extracted from the Spring Framework tests. Tested with the latest GNU
Classpath from CVS as of 2007/05/04 18:00 GMT+2. The required schema can be
found at:

http://www.springframework.org/schema/beans/spring-beans-2.0.xsd

Sun JDK 1.5.0_10 says:

org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was
found starting with element 'foobar'. One of
'{"http://www.springframework.org/schema/beans":description,
"http://www.springframework.org/schema/beans":import,
"http://www.springframework.org/schema/beans":alias,
"http://www.springframework.org/schema/beans":bean,
WC[##other:"http://www.springframework.org/schema/beans"]}' is expected.

GNU Classpath/IKVM.NET parses the document without an error.
