What does 'go version' print?
go version go1.2.1 linux/amd64

What steps reproduce the problem?
Just to http://play.golang.org/p/85oWtwZAq9 and Run.

What happened?
Embedded struct defines XMLName field with xml.Name type and with corresponding field
tag. xml.Marshal ignores this XMLName field from embeded struct and outer tag is
generated from object's struct type name.

What should have happened instead?
Documentation for xml.Marshal says:
- an anonymous struct field is handled as if the fields of its
  value were part of the outer struct.
So I expected that XMLName of type xml.Name from embedded struct should be marshaled as
xml tag name.

Please provide any additional information below.
