[go-nuts] Bug? : xml.Marshal() putting chardata/innerxml inside array

I have a short example that seems to show a bug with xml.Marshal():

http://play.golang.org/p/KuGg_5x13n


I am marshalling the structs Set and Set2 (defined below). The results for
Set seem to be wrong. Using Set2 provides a workaround for Set, but I
think the Set example is still a bug. (The example behaves similarly when
using the attribute "innerxml" instead of "chardata".)

type Set struct {
A [2]string `xml:"A>B"`
S string `xml:",chardata"`
}

type CT struct {
D [2]string
}

type Set2 struct {
C CT
S string `xml:",chardata"`
}

The output is as follows:

<Set>

<A>
<B></B>
<B></B>
Wrong?
</A>
</Set>

<Set2>
<C>
<D></D>
<D></D>
</C>
Right?
</Set2>
