Falha de Esquema: O elemento pai: 'imposto' não estava esper

Bom dia a todos!

Estou com um problema para autorizar um documento na SEFAZ de Pernambuco.

Eu sou da T.I e o pessoal do fiscal esta gerando a nota com CFOP 6949 e NatOp Outras saidas e estamos recebendo a rejeição "Falha de Esquema: O elemento pai: 'imposto' não estava esperando o elemento 'PIS'. O elemento esperado é: 'ISSQN'".

Poderiam nos auxiliar por gentileza a identificar o erro?

Acredito que seja o CST. No meu caso aqui esta utilizado o 400 para emissão de notas e estava dando o mesmo erro, quando mudei para 060 passou.
