Documentation about map.js and map.html in templates is missing

I need some help, In my project i used the normal kind of templating with a default layout and every other extends this.
- When adding a map to lets say a `profile.html` which **extends** `layout.html`, how can i add `mymap.js` to the `` tag if this profile page does not have a head, only the one from the layout?
- If i add this `mymap.js` to the layout, my pages will definitely crash because i am sending this resource only from the profile app context.

Do you have a special way for this situation or is there a workaround?

Thank you.
