13 | * <p/> |
14 | * <p> In this frame any type of file can be encapsulated. After the header,<br> 'Frame size' |
15 | * and 'Encoding' follows 'MIME type' [MIME] represented as<br> as a terminated string encoded with ISO |
16 | * 8859-1 [ISO-8859-1]. The<br> filename is case sensitive and is encoded as 'Encoding'. Then follows<br> |
17 | * <p/> |
18 | * a content description as terminated string, encoded as 'Encoding'.<br> The last thing in |
19 | * the frame is the actual object. The first two<br> strings may be omitted, leaving only their |
20 | * terminations. MIME type is<br> always an ISO-8859-1 text string. There may be more than one |
21 | * "GEOB"<br> |
22 | * <p/> |
23 | * frame in each tag, but only one with the same content descriptor.</p> |
