I create a dataset from XML with one of the fields defined as below in the schema.

<xsd:element name="hoursworked">
   <xsd:simpleType>
	<xsd:restriction base="xsd:decimal">
		<xsd:totalDigits value="5"/>
		<xsd:fractionDigits value="2"/>
	</xsd:restriction>
   </xsd:simpleType>
</xsd:element>

When I WriteXML back to XML I loose the totaldigits and fractiondigits as seen below.

<xs:element name="hoursworked">
       <xs:simpleType>
           <xs:restriction base="xs:decimal" />
       </xs:simpleType>
</xs:element>

Anyone know how to prevent this?
