Content-length: isn't actually listed in the spec. You are free to use
it as an optional-field though.

In the standard, all text after the "message" is the "body" and no
length is specified. Nothing prevents people from using Content-length:
to specify the body size though.

That is basically it. One paragraph worth noting though is this one:

   "The only required header fields are the origination date field and
    the originator address field(s). All other header fields are
    syntactically optional. More information is contained in the table
    following this definition."

This is also true for 822 so you can't "really" claim [2]822 conformance
without an origination date and originator address. I haven't looked at
how subversion uses [2]822 so it may already do this.

Just letting people know.
