Read it as, for each object that you are checking, if the

And the result MUST match the GRANT or DENY.
For example (1) this GRANT would apply to you if:
you wanted to MODIFY
And the PARTSTAT object had any valule.
and ATTENDEE is <self>.
So for a VEVENT with with UPN 'x':
The VCAR allows you to modify ONLY the one that matches.
BEFORE AND AFTER.

NOT true as only ONE of them match, if <self>
is not 'Z' it does not match the first one.

NOT true as it is only true IF he is the ATTENDEE,
else he can not modify it. And yep - your VCAR allows them to
modify the value of the ATTENDEE, as long as it is already
set to 'x'. And you could modify the value, as long as the
rule still was valid - so the only thing you could modify
it to is 'x'

They could modify all ATTENDEEs from UPN 'x' to UPN 'x'.
All other ATTENDEE values don't match.

'property of components' ?
I read (a) and (b) as the same. If the VALUE of ORGANIZER
is 'x', you can read it.
I don't see your points.
