# Policy Statement:
# This IDN table is derived from the Root Zone Label Generation Rules for Lao
 which may be found at the following URL:
 
 https://www.icann.org/sites/default/files/lgr/lgr-2-lao-script-26jul17-en.html
 
 Repertoire
 
 In addition to the code points listed below, the sequence 0EB2 0EB0 has been
 defined to facilitate implementation of WLE rule follows-vafter-context as a
 context rule.

 As this table is designed to validate registrations at the second-level, the
 repertoire includes Lao digits (U+0ED0-U+0ED9), ASCII digits (U+0030-U+0039),
 and HYPHEN-MINUS (U+002D).
 
 Variants
 
 This LGR defines no variants.
 
 Character Classes
 
 Tag             Members

                 0EA1-0EA3 0EA5 0EA7 0EAA-0EAB 0EAD-0EAE} 
 semi-consonant  {0EBC}

 vowel-above     {0EB1 0EB4-0EB7 0EBB 0ECD} 
 vowel-below     {0EB8-0EB9} 
 vowel-after      {0EB0 0EB2 0EBD} 
 vowel-before    {0EC0-0EC4} 
 sign            {0EC6 0ECC} 
 
 * The "Cf" tag denotes final consonants. Other character classes that have
 been used are semi-consonant, tone-mark, vowel-above, vowel-before,
 vowel-below and vowel-after.
 
 Contextual Rules
 
 * leading-combining-mark - Default rule from matching labels with leading
   combining marks.
 * follows-consonant - A semi-consonant must follow a consonant.
 * precedes-consonant - A vowel-before precedes a main consonant cluster.
 * follows-main-consonant - A vowel-above, and vowel-below follow a main
   consonant C.
 * follows-C-tonemark-vabove - A vowel-after follows a main consonant,
   tone-mark or vowel-above.
 * follows-vbefore-consonant-cluster - The sequence (0EB2 0EB0) follows a vowel
   before, and a consonant cluster
 * follows-C-vabove-vbelow - A tone-mark follows a main consonant, vowel-above
   or vowel-below.
 * follows-Cf - The sign 0ECC can only occur after final consonants.
 * repetition-mark-limit - The sign 0EC6 can only occur 0 to 3 times at the end
   of the label.
 
 No context rules apply to "consonant" code points.

 A label containing ASCII digits (U+0ED0-U+0ED9) cannot also contain Lao digits
 (U+0030-U+0039).


A Unicode string MUST NOT contain "--" (two consecutive hyphens) in the third- and fourth-character positions and MUST NOT start or end with a "-" (hyphen). See RFC5891, Section 4.2.3.1.
