XMLStreamConstants.CDATA are not getting generated

XML:
<?xml version="1.0"?>
<foo>
<bar>baz
<cheese id="3"/>
baz
<cheese/>
baz
</bar>
<doc><![CDATA[<foo>]]></doc>
</foo>

Events:

START_ELEMENT: foo:foo

START_ELEMENT: cheese:cheese
END_ELEMENT: cheese:cheese

START_ELEMENT: doc:doc

END_ELEMENT: doc:doc

I expect a XMLStreamConstants.CDATA for <![CDATA[<foo>]]> but getting XMLStreamConstants.CHARACTERS instead.

thanks,
