+/** Class representing a generic security policy
+This class can specify a security policy consisting of either:
+-#	A check for between 0 and 7 capabilities
+-#	A check for a given Secure ID along with 0-3 capabilities
+-#	A check for a given Vendor ID along with 0-3 capabilities
+If multiple capabilities are specified, all of them must be present for the
+security check to succeed ('AND' relation).
+The envisaged use case for this class is to specify access rights to an object
+managed either by the kernel or by a server but in principle owned by a client
+and usable in a limited way by other clients. For example
+- Publish and Subscribe properties
+- DBMS databases
+In these cases the owning client would pass one (or more) of these objects to
+the server to specify which security checks should be done on other clients
+before allowing access to the object.
+To pass a TSecurityPolicy object via IPC, a client should obtain a descriptor
+for the object using Package() and send this. When a server receives this descriptor
+it should read the descriptor contents into a TSecurityPolicyBuf and then
+Set() should be used to create a policy object from this.
+Because this class has non-default constructors, compilers will not initialise
+this object at compile time, instead code will be generated to construct the object
+at run-time. This is wasteful - and Symbian OS DLLs are not permitted to have
+such uninitialised data. To overcome these problems a set of macros are provided to
+construct a const object which behaves like a TSecurityPolicy. These are:
+_LIT_SECURITY_POLICY_C1 through _LIT_SECURITY_POLICY_C7,
+_LIT_SECURITY_POLICY_S0 through _LIT_SECURITY_POLICY_S3 and
+_LIT_SECURITY_POLICY_V0 through _LIT_SECURITY_POLICY_V3.
+Also, the macros _LIT_SECURITY_POLICY_PASS and _LIT_SECURITY_POLICY_FAIL are provided
+in order to allow easy construction of a const object which can be used as a
+TSecuityPolicy which always passes or always fails, respectively.
+If a security policy object is needed to be embedded in another class then the
+TStaticSecurityPolicy structure can be used. This behaves in the same way as a
+TSecurityPolicy object but may be initialised at compile time.
