True, the path attribute 
field itself can be left out.  The text should be changed.

 From a first time reader point of view ...

The top of page 13 says:

"A variable length sequence of path attributes is present in every UPDATE."

Is this really true, given that later, in the second to last paragraph 
of this section (4.3):

"An UPDATE message might advertise only routes to be withdrawn from 
service, in which case it will not include path attributes or Network 
Layer Reachability Information."

This could be confusing to a first time reader.

The path attribute length is present in every UPDATE, the path attribute 
field itself can be left out, both according to the description of the 
minimum length of the UPDATE message and (implied?) in the picture of 
the UPDATE message at the beginning of section 4.3.
