xml namespace is still not ok

[suntong]

based on subchen#5

which strips xml namespace

version="1.1"
inkscape:version="0.92.1 r15371"

as

version="1.1"
version="0.92.1 r15371"

However, with the added xml namespace support, it is still not working as expected:

https://play.golang.org/p/sNzrDX6tXwQ

func main() {
	fmt.Println(svgData)

	fmt.Println("---------------------------------")

	doc := xmldom.Must(xmldom.ParseXML(svgData))
	fmt.Println(doc.XMLPretty())
}

...

becomes

So it is still an XML v1 Dom, with simple hack to allow single namespace.

Not suitable to handle XML v2 samples that have multiple namespaces.
