Request for useful error message on "type:string"

Problem statement

if a swagger is missing a space in "type: string" and is written "type:string" swagger generate server produces "json: cannot unmarshal string into Go struct field SwaggerProps.definitions of type struct { spec.SchemaProps; spec.SwaggerSchemaProps }" Something like "Missing space in 'type:string' would be a better error message
