Abstract: Techniques for allowing cross-document communication are provided. In one approach, a child document of a parent document communicates with another child document of the parent document. A child document may correspond to a frame element within the parent document. The communication may occur directly or indirectly through the parent document. In another approach, an ancestor document communicates with a descendant document that is two or more degrees of separation away from the ancestor document. The communication may occur directly or indirectly through one or more intermediate documents. In both approaches, one document may send out one or more discovery messages that request identities of sibling documents, descendant documents, or ancestor documents.
