PM20826: StAX XMLStreamWriter is outputting the wrong value

Error description

WebSphere Application Server v7.0.0.11 XMLStreamWriter is
outputting the wrong value. The serializer is omitting a
required namespace prefix as follows:

<test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
nil="true"></test>

This causes the document to be invalid. The expected valid
document should look like the following:

<test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:nil="true"></test>

Problem summary

****************************************************************
* USERS AFFECTED:  All IBM WebSphere Application Server V7.0   *

****************************************************************
* PROBLEM DESCRIPTION: XMLStreamWriter is omitting required    *
*                      namespace prefixes.                     *
****************************************************************
* RECOMMENDATION:  Install a fix pack that contains this APAR. *
****************************************************************
When requested to serialize XML attributes the IBM
XMLStreamWriter will omit required namespace prefixes if the
application did not explicitly provide them.

For example, the XMLStreamWriter would incorrectly write:

<test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" nil
></test>

instead of:

<test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:nil="true"></test>

Without the "xsi" prefix the "nil" attribute is not bound to
the correct namespace.

Problem conclusion

When no prefix has been explicitly specified for an attribute,
an XMLStreamWriter implementation is required to use its
namespace context to determine a prefix to write. The IBM
XMLStreamWriter was not performing this lookup and would
always write the attribute without a prefix. This issue was
fixed by adding a prefix lookup call to the namespace context
within the XMLStreamWriter method which writes the attribute.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.15.  Please refer to the Recommended Updates
