Generate a complete WebVTT specification reference by consolidating W3C and MDN sources to cover formatting, timing, cue structure, markup, regions, and blocks, producing a self-validation report with rule counts and completeness assessment.
Full WebVTT spec coverage requires documenting all 8 markup tags (c, i, b, u, v, lang, ruby, timestamp) and all 8 cue settings (vertical, line, position, size, align, region), alongside HTML entities and REGION block properties.
Identify gaps in WebVTT coverage by generating a self-validation report that assesses completeness, counts extracted rules, attributes sources per rule, and flags missing formatting, timing, or markup specifications.
WebVTT specification validation includes complete documentation for STYLE blocks, NOTE blocks, and REGION block properties, ensuring exhaustive coverage of all optional structural elements defined in the standard.
A validated WebVTT spec reference consolidates authoritative sources including W3C WebVTT and MDN, supplemented by targeted web findings to ensure comprehensive coverage of formatting, timing, and markup rules.
WebVTT validation generates 50+ RULE-XXX specifications with unique IDs and test patterns, alongside 12+ IMPL-XXX requirements, providing granular coverage of formatting, timing, and markup constraints.
