[CHH] I took a look at this. Using syntactically correct header fields would make the example quite messy, due to the length of the header fields, so my suggestion would be to instead add the following paragraph to the general section of the examples:

	"NOTE: The examples do not show the actual syntactical encoding of the request lines, response lines
	and the Via header fields, but rather a pseudo code in order to identity the message type and to 
	which entity a Via header field is associated."
