1. A computer-implemented method for validating access to a first element within a group of related elements, comprising: associating, by a computing device capable of network navigation, a security context with each element within the group of related elements; wherein the group of related elements is generated from the same markup domain; verifying, by the computing device capable of network navigation, access to the first element when the security context associated with the first element permits access to the first element; and invalidating, by the computing device capable of network navigation, access to the first element when the security context associated with the first element does not permit access to the first element; wherein all elements that could be generated from a markup domain are associated with the same security context; and wherein the security context associated with the first element comprises an in-memory component.
