Hopefully this is the right group.

I am getting the following exeption:

Member 'PPRP602AType.RPLY_HEADER' hides inherited member
'REPLYType.RPLY_HEADER'
, but has different custom attributes.
  at
System.Xml.Serialization.StructMapping.FindDeclaringMapping(MemberMapping
member, StructMapping& declaringMapping, String parent)
  at System.Xml.Serialization.StructMapping.Declares(MemberMapping member,
Stri
ng parent)
  at
System.Xml.Serialization.XmlReflectionImporter.ImportStructLikeMapping(Str
uctModel model, String ns)

The 'REPLYType.RPLY_HEADER' is abstract and specified as:

    public abstract class REPLYType
    {
        #region Accessor Functions
        public abstract RPLY_HEADERType RPLY_HEADER
        {
            get;
            set;
        }
        #endregion
    }

Then I derive from there

    public sealed class PPRP602AType : REPLYType

and implement the abstract property:

        #region Private Members
        private RPLY_HEADERType _RPLY_HEADER;
        #endregion
        #region Accessor Functions
        [XmlElement(ElementName="RPLY_HEADER_PPRP602A")]
        public override RPLY_HEADERType RPLY_HEADER
        {
            get
            {
                return _RPLY_HEADER;
            }
            set
            {
                _RPLY_HEADER = value;
            }
        }
        #endregion

What am I doing wrong? Why the serialization exception?

Thank you.
