I presume element should be defined in your xsd.
Presumably, you have a schema for the response element, where it has a reference to the error element, which is in a separate schema (unfortunately, schemas cannot have more than one namespace in the same file). The separate schema file with the error element will have no targetNamespace.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
