Alternatives for using ETags

Dear all,

[[
LDP 1.0. 4.4.2 [...] LDPR servers MUST respond with status code 412 
(Condition Failed) if ETags fail to match if there are no other errors 
with the request.
]]

There are other alternatives for using ETags apart from using the 
If-Match header, i.e., If-None-Match header. The specification should be 
clear about this, either disallowing its usage, advising against its 
usage or allowing its usage.

Proposal:

Rewrite clause 4.4.2 covering the other potential cases (If-None-Match 
and If-Range) and saying whether the alternatives should/should not be used.

Kind regards,
