Usage of javax.inject.Named with javax.annotation.ManagedBea

Usage of javax.inject.Named with javax.annotation.ManagedBean
Taken from the following:

http://www.primefaces.org/showcase-labs ... neMenu.jsf

Why do I have to use @ManagedBean to get it to work?
If I use just @Named it does not work? Am I causing a problem by using them both together?
What is the difference between @Named and @ManagedBean?

// PlayerConverter.java
@FacesConverter("playerConverter")
public class PlayerConverter implements Converter, Serializable {
...
}

// AutoCompleteBean.java
@SessionScoped
@Named
@ManagedBean
public class AutoCompleteBean implements Serializable {
...
}

@Named and javax.enterprise.context.*Scoped should be used with CDI, @ManagedBean with plain JSF.
