Rails Paperclip XML POST File

Question

I am able to 'POST' to a Rails application (with Paperclip) using XML instead of the standard web form (trying to do it from another Ruby script). However, I would like to include a binary file.

Is there any way to include the binary data within an XML tag? Or can I do something like B64 encode the data on the client and then decode it before it hits the Paperclip plugin?

UPDATE:
The browser sends a POST with this data (among others):

Content-Disposition: form-data; name="upload[upload]"; filename="foo.jpg" 
Content-Type: image/jpeg

I'd like to replicate that, but within XML
