encoding/xml: typo in docs

[ShawnMilo]

The documentation of func Unmarshal states:

Unmarshal uses a case-sensitive comparison to match XML element names to tag values and struct field names.

Unless I'm really confused about something, that should be "case-insensitive" instead. At least, that's my experience with using encoding/xml and encoding/json.

The documentation is accurate. The field won't match if the XML element's case doesn't match. See http://play.golang.org/p/9oZIgl9n3X where Name is an empty string after unmarshalling.
