Following up on my own previous post,

The description of Permission has this line in the documentation:

GenericRead     YesNoType       specifying this will fail to grant read access

What does that description mean? The name suggests that I can grant GenericRead 
and that will grant, well, "Read" in the sense of the security tab of the 
properties pane on a file, but ... "fail to grant"?? What does "specifying" 
mean? What permissions do I grant to allow a group or user to *just* read a 
static configuration file? I've determined through experimentation that (1) 
below is not enough, and that (2) *is* that using Permission overrides 
everything else and that (3) yes, you can use a group, so I suppose I don't 
need that information still ...

Subject: Permission

(1) If I grant Read, ReadAttributes, ReadExtendedAttributes to two users based 
on a Permission element, what permissions do other users have?
(2) Are the permissions exhaustive for those users? If not, how do I clear 
write access? Do I somehow have to use an explicit deny?
(3) Can the User attribute be used with a local group as the value of the 
parameter instead?

Finally, is the section in the Wix 3.5 documentation wrong on the difference 
between Permission and Util:PermissionEx? Or is the otherwise excellent book by 
Nick Ramirez wrong? The latter seems to describe Permission when talking about 
Utils:PermissionEx if the built in docs are to be believed.
