Os atributos predefinidos incluídos neste SDK são apresentados alfabeticamente na tabela a seguir. Cada atributo tem um nome, um identificador global e um tipo de dados, conforme definido pelo membro apropriado da enumeração WMT_ATTR_DATATYPE. Alguns atributos não usam um tipo de dados simples ou são formatados de acordo com uma estrutura. As entradas para esses atributos listam um nome de estrutura na coluna de tipo de dados com o tipo de dados usado para definir o valor entre parênteses.
