URL: http://issues.apache.org/jira/browse/WSCOMMONS-49
Project: WS-Commons
Type: Bug
Components: XmlSchema
Environment: Windows XP SP2
Reporter: Brent Ulbricht
If the appinfo element does not include a source attribute and does not have
any content
a NullPointerException occurs.
<simpleType name="emptyAppinfo">
<annotation>
<documentation source="http://test/source/doc";
xml:lang="en">testing987</documentation>
<appinfo/>
</annotation>
<restriction base="string">
<length value="1"/>
</restriction>
</simpleType>
java.lang.NullPointerException

The documentation element (handleDocumentation method) in SchemaBuilder has
logic to protect against this by checking if the
markup variable is null.
