2) Section 4.3

Following item to be added to the guidelines:

A Content Transformation Proxy receiving a response that contains a
non-empty meta-tag "Copyright" MUST NOT restructure or recode the
content, nor dependent resources (such as pictures or videos, or other
textual content).

Rationale: The following content alterations may constitute willful
copyright violations:
a) Insertion of additional links, advertisements, navigation elements
(e.g. scroll bars), or extraneous content.
b) Modification of the look and feel (e.g. through reorganization of
the page, filtering out elements such as pictograms).

The following alterations may also constitute defacement of trade
marks and other registered elements:
c) Changing the representation of trademarks, logos and other
registered design elements, as a change in the representation may
affect its legibility, the colours or the colour palette.

The following alterations may also constitute disactivation of or
bypassing IPR protections:
d) Re-encoding images or videos which embed steganographic IPR
protection information may eliminate or render ineffective these
mechanisms.

A copyright meta-tag, in the absence of any other indication, is
enough to signal that the content must not be transformed. This
meta-tag is widely used in the WWW, and its inclusion in content as a
meta-tag (invisible to end-users) is precisely intended to control
automatic processing in the delivery chain.

WG Notes: See: http://www.w3.org/2008/10/20-bpwg-minutes.html#item18 Final resolution: - re. LC-2020, resolve no, the presence or absence of a Copyright is not a clear indication of the rights associated with the page

Resolution: We think that the presence or absence of a Copyright is not a clear indication of the rights associated with a Web page.
