> I am using the code generation tool from approx. 11/1/2007 Axis2/Java nightly snapshot.  I am using it to generate C databindings
> My generated adb databinding code is writing elements in the serialize method even when minOccurs="0".  I think if anything has a minOccurs="0", the generated serialize should check if the element has been provided by surrounding the code block with an "if ( foo-element !- NULL )".  Otherwise, the program will crash if the optional element has not been provided. 
> I have a datatype defined as follows:
>   <complexType name="Foo">
>     <sequence>
>       <element name="foo-element" type="foo_type"
>           minOccurs="0">
>       </element>
>     </sequence>
>   </complexType>
> In my serialize method I'm seeing something like this:
>                         start_input_str = "<ns2:foo-element";
>                             
>                         start_input_str_len = axutil_strlen(start_input_str);
>                         end_input_str = "</ns2:foo-element>";
>                         end_input_str_len = axutil_strlen(end_input_str);
>                      
>                             axutil_stream_write(stream, env, start_input_str, start_input_str_len);
>                             
>                             adb_foo-element_serialize(_Foo->foo-element, 
>                                                                                  env, current_node,
> 					AXIS2_FALSE
>                                     );
>                             
>                             axutil_stream_write(stream, env, end_input_str, end_input_str_len);
