JOSM validation "missing tag - alternative name without name" is false positive for [lock_name=*]

[AnkEric]

Wikipedia: Lock (water navigation), a device for boats to transit between different levels of water.
[lock_name[ is the name for the lock.
[lock_name] is not an alternative name (e.g. loc_name, reg_name, alt_name).
So a lock having [lock_name=*] is not missing a [name=*] tag.
The lock has only one name, e.g: [lock_name=Tolhuissluis].
If the waterway has both [lock_name=Tolhuissluis] and [name=Amstel-Drechtkanaal] then name applies to [waterway=canal].
If a [waterway=canal] has no name than that's another issue (warning?). But not all waterways do have a name (ditch, drain).
