The <AccessControl> element is the root of an XML-based access control policy that prevents access to a resource unless the user's session satisfies the policy. It's a simple, boolean-capable language provided as an example of how to implement an access control plugin.

Child Elements

Any one (and only one) of the following elements can appear:

Name

Cardinality

Description

<Rule> 

A single access rule to enforce.

<RuleRegex>

A single regular expression access rule to enforce.

<OR>Exactly one

An operator for combining any number of rules or operators with a disjunction.

<AND>

An operator for combining any number of rules or operators with a conjunction.

<NOT>

An operator for reversing the meaning of a single rule or operator.

Example

The example below would enforce a policy that allows only Ohio State faculty or students, other than a single blacklisted person, if they have authenticated with a password or a time-synchronized token.
