Protocol (sec 2.2) (editorial)

Section 2.2 says:

"""
The update operation must be invoked using the HTTP POST method.
Client requests for this operation must include
exactly one SPARQL update request string (parameter name: 
update) and may include zero or more default graph URIs
(parameter name: using-graph-uri) and named graph URIs (parameter name: 
using-named-graph-uri).
"""

This talks about "parameters" and specifically gives the name 'update'

In the context of a application/sparql-update request, there is no 
"update=" parameter.

Suggestion:

Change:
[[
(parameter name: update)
]]
   to something like:
[[
(either in the body of the message or as parameter name: update)
]]

or simply drop the (...) for this specific item and rely on the subsections.
