+== The messages ==
+All messages are composed of XDR encoded data. (see [http://www.faqs.org/rfcs/rfc1832.html RFC 1832] for a complete description of XDR). XDR basically means: All data is in network byte order and aligned to the nearest multiple of 4 bytes. Strings are encoded as a zero-terminated array of characters,aligned to the nearest multiple of 4 bytes. Floating point numbers (32 or 64 bit) must be encode in the IEEE standard.
 == The header ==
-All messages contain XDR encoded data and have a well defined header which looks like this:
+The header is always 32 bytes long and contains the following fields in exactly that order:
   |'''Magic'''|'''Version'''|'''MsgId'''|'''MsgLen'''|'''ReplyAddress'''|'''ReplyPort'''|'''Callsign'''|'''Data'''|
