+--1 Numerals
+
+-- This grammar defines numerals from 1 to 999999. 
+-- The implementations are adapted from the
+-- [numerals library http://www.cs.chalmers.se/~aarne/GF/examples/numerals/] 
+-- which defines numerals for 88 languages.
+-- The resource grammar implementations add to this inflection (if needed)
+-- and ordinal numbers.
+--
+-- *Note* 1. Number 1 as defined 
+-- in the category $Numeral$ here should not be used in the formation of
+-- noun phrases, and should therefore be removed. Instead, one should use
+-- [Structural Structural.html]$.one_Quant$. This makes the grammar simpler
+-- because we can assume that numbers form plural noun phrases.
+--
+-- *Note* 2. The implementations introduce spaces between
+-- parts of a numeral, which is often incorrect - more work on
+-- (un)lexing is needed to solve this problem.
