Unrecognised relations in Content-Type interferes with content negotiation

The server should at the very least ignore the relations it can't handle and return application/ld+json, or return 406.

先對伺服器執行 curl 範例，並比較不支援的媒體類型參數與空白媒體類型參數的內容協商。追蹤選取回應表示的請求處理流程；當不支援的關係被忽略並回傳 application/ld+json，或請求收到 406 時，即表示完成。
