Parameters not detected with multiple structs in one statement

Problem statement

Noticed while adding Parameters from a package that declares multiple structs in one statement.
Appears that the annotation "//swagger:parameters" needs to be above the "type" keyword
I expected the annotation "//swagger:parameters" to be able to be inserted directly above each struct declaration

Steps to reproduce

This will NOT work. Notice the syntax for declaring multiple structs/types

type (
	//swagger:parameters myOpID
        Request struct {
		//in:body
		//swagger:name -
	        RequestBody struct {
                        //Foo of body
			Foo string `json:"foo"`
                        //Bar of body
                        Bar string `json:"bar"`
		}
	}
)

This will work.

	//swagger:parameters myOpID
       type Request struct {
		//in:body
		//swagger:name -
	        RequestBody struct {
                        //Foo of body
			Foo string `json:"foo"`
                        //Bar of body
                        Bar string `json:"bar"`
		}
	}

Environment

swagger version: 2.0
go version: go version go1.10.4 linux/amd64
OS: Ubuntu 18.04.2 LTS

To get the spec to generate was an easy fix. My main problem is that the documentation has dictated (minimally) how application code is written outside of comment annotations.

FYI: I am new to go so forgive me if I used incorrect terminology
