Hi List, 

I am new to ZSI, and starting to explore the (infinite) SOAP universe ;)

i have some (as i think) rather unusual wsdl file i have to implement
and ZSI fits in perfectly ! - thanks for the great work !

well, here is what i want to do: 

my wsdl file defines an attributegroup like this:

      <xsd:attributeGroup name="ValueAttributeGroup">
        <xsd:attribute name="SensorId" use="required" type="xsd:unsignedInt">
        </xsd:attribute>
        <xsd:attribute name="DataType" use="required" type="tns:DataTypeEnum">
        </xsd:attribute>
        ...
      </xsd:attributeGroup>

later on, i have a complex type defined which "enhances" the "xsd:double"
type with the attributegroup:

      <xsd:complexType name="SensorValue">
        <xsd:simpleContent>
          <xsd:extension base="xsd:double">
            <xsd:attributeGroup ref="tns:ValueAttributeGroup" />
          </xsd:extension>
        </xsd:simpleContent>
      </xsd:complexType>

using ZSI-2.0-rc3's wsdl2py gives me the following piece of python code
in *_types.py:

    class SensorValue_Def(ZSI.TCnumbers.FPdouble, TypeDefinition):
        # ComplexType/SimpleContent derivation of built-in type
        schema = "http://www.myapp.org/V01"
        type = (schema, "SensorValue")
        def __init__(self, pname, **kw):
            if getattr(self, "attribute_typecode_dict", None) is None: self.attribute_typecode_dict = {}
            # attribute handling code
            ZSI.TCnumbers.FPdouble.__init__(self, pname, **kw)
            class Holder(float):
                __metaclass__ = pyclass_type
                typecode = self
            self.pyclass = Holder

however, when i create a new "SensorValue" instance via
eg .new_SensorValueList () i need to specify the float value when
instanciating and i am not able to specify the attributes
via .set_attribute_*

grepping the code unveils 

	# TODO: Add derivation logic to constructors. 

in ZSI/generate/containers.py ;)

well, can you please give some hints on what is missing (i.e. how the
definition of the above mentioned class should look like), and how it
can be implemented ... i am willing to give it a try ;)

thanks for the great work !

regards,
marcus.
