Abstract
A sending entity creates a structured document and communicates it to a receiving entity includes a transform to ensure document elements are not moved during communication. The structured document comprises a root element and a set of child elements. A child element is protected by a digital signature, prior to being positioned within the document. This element includes a sending entity security policy. The receiving entity includes a transform that determines whether the signed element is in a given position within the received document. The transform evaluates the data string against a set of ancestor elements of the signed element to determine whether the signed element is in the given position. If so, the transform preferably outputs the signed element itself. If the transform determines that the signed element has been moved, however, preferably it outputs a given value other than the signed element.
