Fixed example
The upload service responds with both a PUT and a GET URL wrapped by a <slot> element. The service SHOULD keep the file name and especially the file ending intact. Using the same hostname for PUT and GET is OPTIONAL. The host MUST provide Transport Layer Security (&rfc5246;).
The <put> element MAY also contain an unlimited number of <header> elements which correspond to HTTP header fields. Each <header> element MUST have a name-attribute and a content with the value of the header.
