- Adiciona validação de restrição de mídia (video/mp4 ou audio/mp3)
- Adiciona detecção de duplicação de label/caption
- Adiciona validação de ocorrência única (0 ou 1 por elemento)
- Adiciona verificação de incompatibilidade com alt-text='null'
- Implementa suporte completo a i18n (msg_text, adv_text, adv_params)
- Atinge 100% de conformidade SPS 1.10 para <long-desc>

- Adiciona long_desc_count usando node.findall() no modelo
- Remove dependência de XML truncado na validação de ocorrência
- Normaliza whitespace consistentemente na detecção de duplicação
- Adiciona testes para casos extremos e validação de contagem

Resolve: falsos negativos em XML > 200 chars e duplicação com espaços
variados.
