query_to_xml nulls set to false

I am using query_to_xml with nulls set to false in postgresql 9.0.4. (I
believe the behavior was also present in 8.4.)

The documentation for query_to_xml says that if set to true, nulls with
be treated with xsi:nil="true" and "An appropriate namespace declaration
will be added to the result value. If false, columns containing null
values are simply omitted from the output."

This suggests to me that if set to false, there should be no added
namespace declaration, but, in practice, the xsi namespace is present.

Is this the designed, intentional behavior or accidental?
