Help creating XML-Schema from iSeries PF

All

I'm quite new to XML and maybe there is a chance that I do not fully understand 
the way I am supposed to do this.

I have created a Connection in database explorer
Imported the table descriptions into a project in WDSC

Everything is Ok

Character fields in iSeries are defined as Character columns.
Packed fields in iSeries are defined as Decimal columns with correct scale and 
precision.
Signed fields in iSeries are defined as Numeric columns with correct scale and 
precision.
Text from DDS keyword COLHDG is retrieved and put as Comment on column in WDSC.

I generate a XML-Schema and puts it in another project. When I generate the 
schema I get following

Character field sample
        <xsd:element name="FIELD1">
          <xsd:simpleType>
            <xsd:restriction base="xsd:string">
              <xsd:length value="40"/>
            </xsd:restriction>
          </xsd:simpleType>
        </xsd:element>

Packed field sample

       <xsd:element name="FIELD2">
          <xsd:simpleType name="decimal">
            <xsd:restriction base="xsd:anySimpleType"/>
          </xsd:simpleType>
        </xsd:element>

Signed field sample
        <xsd:element name="FIELD3">
          <xsd:simpleType name="decimal">
            <xsd:restriction base="xsd:anySimpleType"/>
          </xsd:simpleType>
        </xsd:element>

Packed or signed filed gets the same type without any scale or precision
Comment on column is missing in the element description.

What can I do to get the missing parts into the XML-Schema?

Best regards and thanks in advance
