When generating the schema from my JAXB annotated classes, the annotation
@XmlElementWrapper(nillable=false) is not generated with the attribute
"minoccurs=0."

This appears to be related to the fact that my XmlElementWrapper is wrapping
XmlElementRefs:

  @XmlElementWrapper(name = "wrapper", nillable = false)
  @XmlElementRefs( {. . . })

The generated schema is as follows:

  <xs:element name="wrapper">
    <xs:complexType>
      <xs:choice maxOccurs="unbounded">
        <xs:element . . . />
        . . .
      </xs:choice>
    </xs:complexType>
  </xs:element>

However, when I use the same XmlElementWrapper annotation to wrap an
XmlElement, the generated schema does include the attribute "minoccurs=0."

Is this a bug, or is there another annotation or attribute that can
accomplish this?
