Before filing a bug, please check whether it has been fixed since the
latest release. Search the issue tracker and check that you're running the
latest version of Go:

Run "go version" and compare against
http://golang.org/doc/devel/release.html  If a newer version of Go exists,
install it and retry what you did to reproduce the problem.

Thanks.

What steps will reproduce the problem?
If possible, include a link to a program on play.golang.org.
1. Download http://play.golang.org/p/5AGYi95HzX
2. Run go vet on it
3.

What is the expected output?
foo.go:14: method UnmarshalXML(wrong int) should have signature
UnmarshalXML(*xml.Decoder, xml.StartElement) error

What do you see instead?
foo.go:10: method MarshalXML(e *xml.Encoder, start xml.StartElement) error should have
signature MarshalXML() ([]byte, error)

Which compiler are you using (5g, 6g, 8g, gccgo)?


Which operating system are you using?


Which version are you using?  (run 'go version')


Please provide any additional information below.
The MarshalXML signature it checks is that of the interface that was removed before Go
1.0, UnmarshalXML isn't checked at all.
