VAST and VMAP Schemas

Video Ad Serving Template (VAST) is the XML contract between video players and ad servers; VMAP (Video Multiple Ad Playlist) schedules ad breaks around content. IAB Tech Lab publishes XML Schema definitions for VAST 4.1, 4.2 and 4.4 and VMAP 1.0 in its GitHub repositories (the vast_4.3.xsd file in the repository is empty upstream).
