This comment is posted on half of Bill Jouris < bill.jouris@insidethestack.com>   ------------------------------------------------------------------------------------------------------ Section 5.1 paragraph 1 (page 9) notes that SLDs can include a variety of code points not allowed in TLDs -- for example digits. These were not considered when identifying variants for TLDs. How will variants involving these code points be identified? (As an example, the digit 1 (Unicode 0031) is a homoglyph of the Latin Small Letter L (Unicode 006C) in many fonts.)
