Sorry Ken, but I cannot understand you here.
As I said, I was referring myself to NamesList-3.0.0.txt
because Dr. Freytag explained us a while ago that this is better source
about the meaning of a character than the database is.
As far as I know, this file has not been updated since Aug 25, 1999.
This file says:
          * Marshallese
          x (modifier letter vertical line - 02C8)

I also checked the database. The most recent version I can see is 3.0.1
Which says:

I do not know the exact technical term that is to be used in this context,
but the /mention/ "Tonos" added after the English name of the character
definitively looks like a /note/ to me.

I know Unicode and ISO/IEC 10646 have to be aligned, so I understand
perfectly this can be the very reason why this /mention/ is ever present.
I also understand such a note could not be removed, how irrelevant it is,
because of the backward compatibility problems. No problem with me here.
My only point is that, when someone seeks after "tonos" in NamesList,
there are two good things that are present, and another which is not:
- good thing, as I said, under U+0301, it is said this is the Greek tonos;
- good thing, under U+0344, it is said this character is deprecated, and
  it is canonically decomposed as U+0308 U+0301;
- another missing point is that, under U+030D, no mention exists to explain
  that despite the name and /mention/, this is *not* the Greek tonos
