It was once proposed:

Trademark concerns require a sixty-day publication period, prior to
authorization of an SLD under a gTLD. Random-number domain
names will be available for immediate use. ISO 3166-based TLDs
are encouraged to make similar domain names available under
their own portion of the name space. An international trademark-
specific domain space should be created, called .tm.int, to
accommodate the international character of some trademarks.
