This document defines a standard for the authoring of declarative data content intended to be combined primarily with video and/or audio services, and distributed to data-capable television signal receivers. The data essence defined in this standard may be used in conjunction with that defined in the Declarative Data Essence ¿ Content Level 1 specification [DDE-1]. It will be possible for applications authored according to the essence specified herein to execute on the vast majority of currently fielded interactive digital television systems, either directly or after being transcoded. Declarative content is generally nonprocedural, and most commonly in the form of HTML. However, procedural scripting is also defined.
