Further Investigation:
From all documentation I can find, it seems that @XmlMixed is always meant to be used in conjunction with @XmlElementRef, @XmlElementRefs or @XmlAnyElement. We're still trying to determine if @XmlMixed by itself is a valid use case.
The RI does support marshalling but does not seem to be able to unmarshal:
Marshal:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<foo>First Second Third</foo>
Unmarshal:
Exception in thread "main" javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"#document"). Expected elements are <{}foo>
EclipseLink does support marshalling and unmarshalling, but on the unmarshal we are concatenating all of the values together:
Marshal:
<?xml version="1.0" encoding="UTF-8"?>
<foo>FirstSecondThird</foo>
Unmarshal:
[FirstSecondThird]

Test Case
If it turns out to not be a valid use case (I couldn't find documentation that said either way for certain) then that's also a great resolution to this. This was the origination of my investigation into the matter: http://www.eclipse.org/forums/index.php?t=rview&goto=692985#msg_692985 Seemed to imply that @XmlMixed *was* valid by itself. One comment and one question:
> <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
> <foo>First Second Third</foo>
I'd expect the above to unmarshall as one text node, since there are no intervening other nodes. Would that make sense?
In addition, what if anything would the following mean?
@XmlMixed
List foo;
It could either:
- default to @XmlElement, and ignore the @XmlMixed annotation.
- default to @XmlAnyElement, taking the @XmlMixed annotation.
- default to nothing, or an error.
- ... ?

The following example: public class Foo { @XmlMixed public List content; } can not be captured as it exists in an oxm file. It does not capture wild card (@XmlAnyElement) or other (@XmlElementRef) content, so it cannot be mapped as either xml-any-element or xml-ref(s).
