These requirements are about display, not localization.
[18] is about features of some scripts (*not* languages) that might
not be supported in all display devices. However, there is nothing
"local" about bi-directional writing.
[19] is also about display because the "." is used in the application
service layer only, not on the wire.
[20] doesn't contain a requirement.
I propose that this section header be dropped and the three
requirements be replaced with a single one:
The protocol should not place any restrictions on the application
service layer. It should only specify changes in the DNS service
layer and within the DNS itself.
