title: DocuSign attaching a document to an envelope
body: <p>I was wondering if it was possible to attach a document or documents to an envelope when sending envelopes via SOAP API? I have used the api to create an Attachment object and added the bytes but when I attach to the envelope the status envelope attachments comes back as null and when I look at the docusign email there is no attachment( I'm assuming is due to the fact that attachment returns as null in the status, but when I debug it the attachment is clearly there. Can a sender attach documents to an envelope?</p>
  
  <pre><code>Attachment attachment = new Attachment(){
     Data = "bytes",
     Label = "name",
     Type = "Document"
  };
  newTemplate.Envelope.EnvelopeAttachment = new Attachment[] { attachment };
  </code></pre>
  
  <p>Finally I attach the attachment to the envelope and send.</p>
  
  <p>Thank you</p>
