* use 'type' = 'localfile' for this to be in line with the other detail retrieval classes, but that
* could break existing filters on types 'jwplayer', 'mediaelementjs' etc which have been used up to
* now for local files from various sources.
*
* The 'attachment_id' (int) key is used to refer to local attachment posts.
* The 'file_path' (string) key is used to remember the path to the file we determined exists.
*
* The local property file_url always *has* to be set, of the local properties file_path and
* attachment_id only one or the other is expected.}}
