Marshal XML with xmlns:xsi

[Matope Ono]

Hi, I have a trouble with XML Marshaling/Unmarshaling.

http://play.golang.org/p/rxXydio31M

I want to convert between following XML and my struct.

Figure.1

    <People>
      <Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Student">
        <ID>2222</ID>
        <Name>Alice</Name>
      </Person>
      <Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Student">
        <ID>3333</ID>
        <Name>Bob</Name>
      </Person>
    </People>

 Figure.2

type Person struct {
Xmlns_xsi string `xml:"xmlns xsi,attr,omitempty"`
Xsi_type    string `xml:"http://www.w3.org/2001/XMLSchema-instance type,attr,omitempty"`
ID              string `xml:",omitempty"`
Name         string `xml:",omitempty"`
}
type People struct {
Person []Person `xml:"Person,omitempty"`
}

I could unmarshal perfectly. All values I wanted are in my Person struct.

But marshal didn't output format that I wanted to. I wanted xml like Figure.1

In Figure.3, many unintended attributes on Person element. ("_xmlns" ?)

Figure.3

----------- unmarshal -----------
{Person:[{Xmlns_xsi:http://www.w3.org/2001/XMLSchema-instance Xsi_type:Student ID:2222 Name:Alice} {Xmlns_xsi:http://www.w3.org/2001/XMLSchema-instance Xsi_type:Student ID:3333 Name:Bob}]}
------------ marshal ------------
<People>
  <Person xmlns:_xmlns="xmlns" _xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:XMLSchema-instance="http://www.w3.org/2001/XMLSchema-instance" XMLSchema-instance:type="Student">
    <ID>2222</ID>
    <Name>Alice</Name>
  </Person>
  <Person xmlns:_xmlns="xmlns" _xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:XMLSchema-instance="http://www.w3.org/2001/XMLSchema-instance" XMLSchema-instance:type="Student">
    <ID>3333</ID>
    <Name>Bob</Name>
  </Person>
</People>

What do I need to do to marsha/unmarshal such a XML?

Thanks.

I hit this same problem a few weeks ago, and issue #7535 was filed.
