avoid the use of 'mixed=true' in xml schema

Question

I am using xjc to convert a schema to java classes. When I am using mixed=true in the schema I am losing the access method for child nodes instead there is a single general content access method.

Is there a way to rewrite the schema without using mixed=true. There is no way that I can change the xml so I have to customize the schema.

Schema

XML camera or camera>
