XmlIO documentation example should return Pcollection of Record Class not String

Currently the example listed for XmlIO.Read located at https://github.com/apache/beam/blob/master/sdks/java/io/xml/src/main/java/org/apache/beam/sdk/io/xml/XmlIO.java (line 88 and also at line 129) returns a PCollection of Strings instead of a PCollection of the record class which is a Jaxb annotated class.
