Hi Alex,

    Unfortunately, although they look like custom attributes when you apply
them, declarative security demands are not stored as custom attributes in an
assembly. Therefore you won't be able to see them when you reflect over the
custom security. In current releases of the framework, there is no way to
use reflection to access declaritive security, although we are considering
adding this feature to a future version.
