Invalid XML for plist ... successful?

main.go

package main

import (
	"fmt"
	"log"

	"github.com/groob/plist"
)

const cmdPlist = `C "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>Command</key>
	<dict>
		<key>RequestType</key>
		<string>DeviceInformation</string>
	</dict>
	<key>CommandUUID</key>
	<string>a84bb3f9-c3a0-47e2-af01-7c053abedba6</string>
</dict>
</plist>`

type Cmd struct {
	Command struct {
		RequestType string
	}
	CommandUUID string
}

func main() {
	c := new(Cmd)
	if err := plist.Unmarshal([]byte(cmdPlist), c); err == nil {
		fmt.Println(c.CommandUUID, c.Command.RequestType)
	} else {
		log.Fatal(err)
	}
}

Output of running this:

a84bb3f9-c3a0-47e2-af01-7c053abedba6 DeviceInformation

I.e. successfully parses it.
