Yes, that is correct, in XDb1 dbs, each thing can have 0 to many names. While the earlier versions do have errors in its NLI that prevent one from accomplishing as such, one could have used the GUI or API.

Older versions of XDb1 didn't process this correctly. In older versions, to accomplish similar via GUI:

1. Create 'jonah' (there was also an error in processing names with duplicate symbols).

   ---

2. Select node thing/name in tree.
3. Press Ctrl+T to create an instance of name. A new instance appears with its label in edit mode.
4. Type 'jonah' and press Enter.
5. Relate the name 'jonah' as a property/value of john.

   ---

6. Select 'jonah' in the tree.
7. Click 5th ToolBar Btn (tip says 'Relate as value') or Ctrl+L.
8. Select thing/person/john.
9. Click Paste button or Ctrl+V.

Repeat above process to relate additional names to the person.

The node for the person, now displays "john jonah" instead of "john". To see each name individually as a child of the person, check "Name" in the View Menu. Reload by double-clicking him. One now sees:

Before                After
-------------------   ---------------------
thing                 thing
  person                person
    john                  john jonah
      john                  john
      35                    35
                            jonah
        

In XDb1, a name and that which it names are two separate things. With Parenthesis checked in the View Menu, the tree would appear as:

(thing)
  (person)
    (john)(jonah)

      john
      (35)
      jonah

To add a name to a thing via API, one method is:

    T_Val_relate(pJohn, pName_g, "jonah");
