# I am having difficulty with using SOAP with MIME attachments,
# possibly due to a "binary attachment" done outside a soap 
# envelope.

# Can someone tell me what I am doing wrong with this MIME::Entity , 
# so that I do not get an uncorrupted tiff or pdf file?

# The soap service is documented at http://ops.espacenet.com/ ,
# under "Input Examples" as "DocumentRetrieval"- but you probably 
# do not need that, see the code below.

# Thanks.
