XML collection duplicated element names

I'm having trouble getting a case class with a collection field to serialize the way I want.
I have a data model that looks like this:

``` scala
@JsonRootName("document")
case class Document(header: Header)
case class Header(authors: Seq[Author])
case class Author(name: String)
```

And I'm using Jackson to produce an XML:

``` scala
val doc = Document(Header(Seq(Author("Dick Jones"), Author("Bob Morton"))))
val mapper = new XmlMapper()
mapper.registerModule(DefaultScalaModule)
val xml = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(doc)
```

The document that looks like this:

``` xml




Dick Jones


Bob Morton




```

But `` is duplicated with its nested elements. I want the `` tag to contain a list of `` elements.
I can get this output by adding the following annotations to the Header case class:

``` scala
case class Header(@JacksonXmlElementWrapper(localName = "authors") @JacksonXmlProperty(localName = "author") authors: Seq[Author])
```

This serializes the way I want, but when deserializing I get the following exception:

```

Is there something I can do to get this to deserialize properly?
Thanks for your help!
