XML I10-002 Exam - Topic 4 Question 43 Discussion

Question

Select which of the following correctly describes the message reception processing circumstances when a well-formed XML document has been sent/ received. [Transmission] Character encoding for the transmitted XML document is "UTF-16", and no XML declaration has been specified. The media type for transmission is set as "text/xml" without charset parameter. [Receipt] Implementation follows RFC3023 and XML 1.0. The receiving system first identifies the media type, and then processes the XML document. At the point that character encoding has been determined, an XML declaration (including encoding declaration) is appended automatically to the head of the received XML document.
