Novice's Misinterpretation:

"The body (if present) has a length dictated by the magnitude of the header."

Initially I thought perhaps the length (up to 64 bits) of the header could be used to infer the length of the body... but I think what is meant is that the header (in part) explicitly specifies the length of the body. If this is what was meant then I became confused by the use of the word "magnitude" here. Perhaps simply excising "the magnitude of" would make the meaning clearer? Or perhaps I still misunderstand.

I changed that body-length-from-header sentence to read:

The length of the body (if present) is indicated by the number encoded in the header.

How's that sound?

I fixed the other changes. Thanks!
