This issue was originally reported by John Tebbutt and Ashok Malhotra.

  * If an implementation strictly implements a 18 digit decimal
    facility, it cannot accomodate long which requires 20 digits.

  * 18 decimal digits cannot be accommodated in 64 bits.

This item was classified as requirement and discussed, and phase-1
agreement was reached, in the meeting of 2004-04-08
(http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2004Apr/0130.html).

This requirement has been discharged by reducing the required precision
for decimal to 16 digits, and by making the minimum implementation
requirements more precise in various ways.  See also bug 1918 and bug 1919.
