Subject: [ebxml-msg] About Content-ID in examples
Hi, I want to relate what I think is a minor technical issue with the treatment of Content-ID in ebMS. Line 492 of ebMS v1.0.6 states: It is strongly RECOMMENDED that the initial headers contain a Content-ID MIME header structured in accordance with [RFC2045], ... Line 1432 of RFC2045 says: id := "Content-ID" ":" msg-id where msg-id is defined in line 1210 of RFC822: msg-id = "<" addr-spec ">" ; Unique message id The above leads me to believe that the value of the MIME Content-ID header must always be enclosed in angle brackets <>. The examples in ebMS however do not always follow this convention/requirement. Lines 501, 527 do not reflect this understanding whereas lines 558, 2670 and others do. My question is: 'Is it legal to have a value for Content-ID not enclosed within angle brackets?'. Is there another RFC that supersedes this one (RFC2045) that allows this possibility? Hence, are MSHs required to handle both cases? Another related item is about what looks like an error in RFC 2392: A "cid" URL is converted to the corresponding Content-ID message header [MIME] by removing the "cid:" prefix, converting the % encoded character to their equivalent US-ASCII characters, and enclosing the remaining parts with an angle bracket pair, "<" and ">". For example, "cid:foo4%25foo1@bar.net" corresponds to Content-ID: <foo4%25foo1@bar.net> It looks like Levinson in this RFC really mean that "cid:foo4%25foo1@bar.net" corresponds to "Content-ID: foo4%foo1@bar.net" where the hex value of the '%' character is 25. James Galvin has pointed out that ebMS v1.0.6 could refer to RFC2822 (which was released in April 2001 and obsoletes RFC822). Comments and criticisms equally appreciated. Regards, Sanjay Sanjay J.
