golang oddity, XML encode encodes double quote wrong.

README.md

The standard is for double quote (") to be encoded into " But golang seems to encode as the literal entity "

main.go

package main

import (
    "encoding/xml"
    "os"
)

func main() {
    type Person struct {
        FirstName string   `xml:"name>first"`
    }

    v := &Person{FirstName: `"John"`}

    enc := xml.NewEncoder(os.Stdout)
    enc.Encode(v)
}

result.xml

<Person><name><first>&#34;John&#34;</first></name></Person>
