Many extensibility elements have nested sub-elements.  The WSDL Editor's "New
WSDL  Editor Wizard" can't seem to handle nested sub-elements when using the
template feature.  Please see the description below:

Hi,

We are supporting the following hierachy for extensiility elements in JDBC BC as
given below, (Sorry for long mail).

 Binding
        BindingOperation
                 JDBCOperation
                        Jdbc:input
                                jdbc:sql

In this case i have designed my template.xml file as given below, 

 Binding
        BindingOperation
                 JDBCOperation
                        Jdbc:input
                        jdbc:sql                                   
<template name="SelectOperation">
      <wsdlElement name="Binding">
           <extensionElement name="binding">
           </extensionElement>
      </wsdlElement>
      <wsdlElement name="BindingOperation">
           <extensionElement name="operation">
           </extensionElement>
      </wsdlElement>
       <wsdlElement name="BindingOperationInput"> 
            <extensionElement name="input" >
                <extensionAttr name="operationType" defaultValue="select" />
                <extensionAttr name="numberOfRecords" defaultValue="Please
specify a value" />       
           </extensionElement>   
           <extensionElement name="sql" >
               <extensionAttr name="paramOrder" defaultValue="Please specify
parameter order" />
               <extensionAttr name="sql" defaultValue="Please specify sql
statement" /> 
               <extensionAttr name="PKName" defaultValue="Please specify PKName
Column" />
               <extensionAttr name="FlagColumn" defaultValue="Please specify
Flag Column Name" /> 
           </extensionElement> 
      </wsdlElement>
      <wsdlElement name="ServicePort">
          <extensionElement name="address" >
               <extensionAttr name="jndiName"  defaultValue="Please specify a
value"/> 
          </extensionElement>
      </wsdlElement>
  </template>

i am not getting the element jdbc:sql under jdbc:input instead i am getting the
jdbc:sql as sibling to the element jdbc:input.

I tried by adding the jdbc:sql element as part of extension element jdbc:input as,

<wsdlElement name="BindingOperationInput"> 
            <extensionElement name="input" >
                <extensionAttr name="operationType" defaultValue="select" />
                <extensionAttr name="numberOfRecords" defaultValue="Please
specify a value" />       
               <extensionElement name="sql" >
                   <extensionAttr name="paramOrder" defaultValue="Please specify
parameter order" />
                   <extensionAttr name="sql" defaultValue="Please specify sql
statement" /> 
                   <extensionAttr name="PKName" defaultValue="Please specify
PKName Column" />
                   <extensionAttr name="FlagColumn" defaultValue="Please specify
Flag Column Name" /> 
               </extensionElement> 
           </extensionElement>  
</wsdlElement>

In this case i am not getting jdbc:sql view in the design model of wsdl
document. I guess we do not have support for nested elements in this case. I am
wondering whether this is the way to do or is there any other element which I
can make use so that the element <jdbc:sql> becomes child element

Is there any API or the documentation where I can look at how can I design of
the template.xml in my own way for the jdbc?  Can you please point me where can
I look for?
