encoding/xml: failure to handle conflicting tags in different namespaces

[jbardin]

What does 'go version' print?

go1.3.1

What steps reproduce the problem?

Try to decode document with the same tag in multiple namespaces
<example>
    <title>Example</title>
    <link>http://example.com/default<;/link>
    <ns:link xmlns:ns="http://www.w3.org/2005/Atom";>http://example.com/ns<;/ns:link>
</example>`

http://play.golang.org/p/FT56UXolGO


What happened?
main.Example field "Link" with tag "link" conflicts with field
"AtomLink" with tag "http://www.w3.org/2005/Atom link"

What should have happened instead?

It should be possible to decode both tags in this document.

Also, if the name-spaced tag isn't provided, the second "link" element shadows
the first though it's in another namespace.

Comment 3 by glen.newton:

I am also encountering this issue & is impacting my application. Note that issue only
occurs when one of the namespaces is empty. See same example with two explicit name
spaces: http://play.golang.org/p/tpGAWsc_Yo <-- Works OK.

I just ran into this issue working with a legacy SOAP API that had a lot of namespaces in the fields.
