Search the assets path for the assets file.  Asset files must be have unique names and paths.
Also looks for files relative to the current asset that is being processed.
For Example href="../my-other-component/other-component.html" will still be included.
In addition as long as the root extension is correct it will work as well
(index_action.html.erb) will still be included even if you use href="other-component.html"
