An XAccessControlContext is used to make system resource access decisions
based on the context it encapsulates.
More specifically, it encapsulates a context and has methods to check
permissions equivalent to XAccessController interface,
with one difference:
The XAccessControlContext makes access decisions
based on the context it encapsulates, rather than
that of the current execution thread.
Determines whether the access request indicated by the specified
permission should be allowed or denied, based on this context.
The semantics are equivalent to the security permission classes of
the Java platform.

You can also pass a sequence of permissions (sequence< any >) to check
a set of permissions, e.g. for performance reasons.
This method quietly returns if the access request is permitted,
or throws a suitable AccessControlException otherwise.
