At W3C DAPT Candidate Recommendation Draft 26 June 2026, timing, free-text script-event annotation, character/text, and mixing instructions are four separate data-model areas. There is no dedicated emotion, effort or breath field: the closest slots are the free-text Script Event Description (ttm:desc), its small provisional descType registry (pronunciationNote, scene, plotSignificance) and x- user-defined types, plus Rate/Pitch for synthesized speech. No M&E or stem concept appears in the document; mixing is gain/pan. So an agent can use DAPT to keep three kinds of data apart, but must define its own performance-intent convention.

Curator qualifications: W3C DAPT CRD (2026-06-26) keeps timing, free-text script-event description (ttm:desc with descType: pronunciationNote, scene, plotSignificance, x- types), character/text and mixing instructions as separate areas; no dedicated emotion/effort/breath field.
