Application Prefix Registration
You can register a prefix to avoid DIAL name conflicts and reserve a future namespace.
Things to note before registering a prefix:
Name prefixes are not required, they are optional.
A prefix is part of the DIAL name, not a separate entity.
If you register a prefix, it is not strictly necessary to use it in your app names now, but doing so will make communicating and coordinating names among your developers and partners easier.
The recommended convention is reverse domain name (e.g., com.acme, org.domain, etc.).
Remember that DIAL names are only visible to developers at the code level. They are never visible to consumers, so your naming choices (including prefixes) should be simple, intuitive, and as obvious as possible.
