Abstract

trata-se de um primeiro descritor que descreve um ponto de operação. o segundo descritor é um descritor de hierarquia ou um descritor de extensão de hierarquia. o segundo descritor tem um valor de índice de camada de hierarquia igual a um valor do segundo elemento de sintaxe. um primeiro valor de um primeiro elemento de sintaxe no primeiro descritor especifica que um fluxo elementar indicado por um segundo elemento de sintaxe no primeiro descritor, quando não presente em uma lista de fluxos elementares, deve ser adicionado à lista, e um fluxo elementar indicado por um índice no segundo descritor, quando não presente na lista, deve ser adicionado à lista. em resposta à determinação de que o primeiro elemento de sintaxe tem um segundo valor diferente do primeiro valor, adicionar o fluxo elementar indicado pelo segundo elemento de sintaxe, quando não presente na lista, à lista, mas não o fluxo elementar indicado pelo índice no segundo descritor.
