D-009 List: IP Location Services gives standard codes 511 and 512 to 51Degrees, inside the range other lists reserve for vendors. Are they core terms?
What the schemas do
Core terms: 511 and 512 are codes the list names, and the list reserves no vendor range, so its vocabulary is closed.
Options
Why
The list writes no 500+ row, so it reserves no vendor range, and 511 and 512 are two of its codes like 1 to 4. Their place in the numbering is surprising, since other lists reserve 500 and up for vendors, but the table settles what they are.
What we ask the specification to state
Number standard codes below 500, as every other list does, or say that IP Location Services reserves no vendor range and that 511 and 512 are standard codes. An exchange that already uses 511 or 512 as private codes on another list's pattern now collides with a standard one.
