addAttachment does not link the uploaded attachment to the workitem

[s7eph4n]

rtcclient 0.7.0
RTC 6.0.6.1

When adding an attachment, the file is successfully uploaded, but when linking to the workitem the server complains about malformed XML.

To get it to work I fixed _add_attachment_link to use JSON:

    def _add_attachment_link(self, attachment_info):
        headers = copy.deepcopy(self.rtc_obj.headers)
        headers["Content-Type"] = self.OSLC_CR_JSON

        payload = {"rdf:resource": attachment_info["url"],
                   "dcterms:title": ": ".join([str(attachment_info["id"]),
                                               attachment_info["name"]])}
        attachment_tag = ("/rtc_cm:com.ibm.team.workitem.linktype."
                          "attachment.attachment")
        attachment_collection_url = self.url + attachment_tag

        resp = self.post(attachment_collection_url,
                         json.dumps(payload),
                         verify=False,
                         headers=headers,
                         proxies=self.rtc_obj.proxies)
        raw_data = xmltodict.parse(resp.content)

        return Attachment(attachment_info["url"],
                          self.rtc_obj,
                          raw_data=raw_data["rtc_cm:Attachment"])

@s7eph4n Please try to validate your xml file first. Try this online validator.

That's the thing. There is no XML sent by the original code as far as I can tell, instead payload is posted as is.
