While XACML cannot claim to have "proven" uses in this area, it is a practical, mature standard for attribute-based access control. XACML attributes can be construed as RDF properties, leading to possible semantic applications of XACML.

I hear you. However (and that may show my complete ignorance...) is there any access control mechanism out there that has already proven itself in the area of Linked Data deployment that is in the maturity level of standardization? I am a bit concerned about chartering this group with an essentially R&D work while the other goals are much less so...

As much as I would like to have a "tight scope" for this WG, I have to
observe that access control (or more like lack thereof) has often been a
problem in Semantic Web/Linked Data projects I have been involved in.
Particularly fine-grained access control of Semantic Web data.

I fear that deeming access control strictly "out of scope" and hoping that
some (so far unspecified) liaison with other groups to solve this problem
will only result in the issue not being seen as important enough.

I'd suggest to improve the following section and be more explicit
regarding the bigger picture [1]:

2.3 Out of Scope
Several possible standards that are out of scope for this group, such
as those listed below:

   € Access control mechanisms, WebACL, Web Identity

Mention that both authentication and authorisation are orthogonal
issues and hence, in order to stay focused and to be successful, the
WG will not focus on these issues (but liaison with the respective
groups to ensure compatibility and openness).
