Issue Plesk XML Integration API Issue

[Narender Kumar]

Not this is right place to ask this question.
I was developing a integration component for plesk version 1.6.7.0. As per the plesk documentation using the Xsd files. I could see two complexType Element (ServerOperatorType) in two different Xsd files.
Complex Type Element: ServerOperatorType
Files: 1.6.7.0\server_output.xsd, 1.6.7.0\server_input.xsd

My question is that why the same element created in two files. And how it should be used. Please assist?
