I am trying to create a new Document Library using the SharePoint Lists web service. I can create a generic Document Library using the below SOAP:

```
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soap="http://schemas.microsoft.com/sharepoint/soap/">
   <soapenv:Header/>
   <soapenv:Body>
      <soap:AddList>
         <soap:listName>TestLibrary</soap:listName>
         <soap:templateID>101</soap:templateID>
      </soap:AddList>
   </soapenv:Body>
</soapenv:Envelope>

```

However, our site admin has created custom Document Library templates that I am supposed to use. My question is, how do I create a Document Library in SharePoint using a custom Document Library template with web services? I'm assuming I would need to find out the Template ID, but I'm not sure how to find this. Or is there another way?

FYI, I found a list of standard template types [here](http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.splisttemplatetype.aspx).
