This issue was originally reported by Mike Cowlishaw.

Provide a datatype which retains trailing zeroes in the lexical
representation of decimal numbers.  More generally, provide a
*precision decimal* type, in which each value is associated not only
with a magnitude but also with a precision.

Input from Straw Poll O-4

Interacts with RQ-28, RQ-30 (the same proposal discharges all).

Changed to desideratum on telcon 2002-11-21.  The rationale was that
we already have a well developed proposal for this.

(http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2004Apr/0003.html).
We reached phase-1 agreement on canonical forms and keeping a single
NaN.

This item was discussed in the meeting of 2004-05-12
(http://www.w3.org/XML/Group/2004/05/xml-schema-ftf-minutes.html).  A
proposal to reclassify it as a non-goal was discussed briefly, and
postponed until late June.

Proposal:

Latest from Dave Peterson (member-only link)
(http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2002Dec/att-0045/01-precisionDecimal.html)

This requirement was discharged by the inclusion of the precisionDecimal
datatype in XML Schema 1.1.

(See also bug 1912, which relates to one particular aspect of this
requirement.)
