I'm using svcutil to generate classes from service metadata. This XML schema

<xsd:complexType name="FindRequest">
    ...
    <xsd:attribute name="Significance" type="Significance" use="optional" />
  </xsd:complexType>

<xsd:simpleType name="Significance">
    <xsd:list>
      <xsd:simpleType>
        <xsd:restriction base="xsd:int">
          <xsd:enumeration value="1" />
          <xsd:enumeration value="2" />
          <xsd:enumeration value="3" />
        </xsd:restriction>
      </xsd:simpleType>
    </xsd:list>

produces following code:

public partial class FindRequest
    {
        ...
        private int significanceField;

        private bool significanceFieldSpecified;

        [System.Xml.Serialization.XmlAttributeAttribute()]
        public int Significance
        {
            get
            {
                return this.significanceField;
            }
            set
            {
                this.significanceField = value;
            }
        }

        [System.Xml.Serialization.XmlIgnoreAttribute()]
        public bool SignificanceSpecified
        {
            get
            {
                return this.significanceFieldSpecified;
            }
            set
            {
                this.significanceFieldSpecified = value;
            }
        }
}

My questions are:

• Is it possible to make XmlSerializer understand this type of list:

   <FindRequest Significance="1 2 3"/>
  

  For example by using some kind of a flags-style enum:

  public enum EmployeeStatus
  {
     [XmlEnum(Name = "1")]
     One = 1,
     [XmlEnum(Name = "2")]
     Two = 2,
     [XmlEnum(Name = "3")]
     Three = 4
  }
  

• If the answer is yes, Is it possible to make svcutil/xsd.exe generate classes that are serialized that way without changing the schema?
