java - element with default enumeration value -

is possible set default value element type of enumeration?

i tried following:

<xsd:element name="progresstype" type="tns:progresstype" default="type a" nillable="false"/> 

where tns:progresstype enumeration:

<xsd:simpletype name="progresstype">    <xsd:restriction base="xsd:string">       <xsd:enumeration value="type a" />       <xsd:enumeration value="type b" />    </xsd:restriction> </xsd:simpletype> 

however, when i'm instantiating object contains progresstype attribute object.getprogresstype() null.
