The XML Query/XPath Functions and Operators task force decided in its meeting on 12/5 to allow conforming processors to support limited lexical representations for the date and time types. The minutes are at: http://lists.w3.org/Archives/Member/w3c-xml-query-wg/2001Dec/0023.html The precise wording that will be included in the document has not been approved by the task force. A suggested wording is below. We believe it would aid inter-specification coordination if XML Schema would add similar wording as part of the errata. The wording below is based on the wording XML Schema adopted to allow minimally conforming processors to support 18 digits in decimal representations. For a number of the above datatypes [XML Schema Part 2: Datatypes] <file:///C:\xmlspecs\query\operators\FromNorm\ashok\xquery-operators.htm l> extends the basic [ISO 8601] <file:///C:\xmlspecs\query\operators\FromNorm\ashok\xquery-operators.htm l> lexical representations, such as YYYY-MM-DDThh:mm:ss.s for dateTime, by allowing more than four digits to represent the year field -- no maximum is specified -- and an unlimited number of digits for fractional seconds. For this specification, all minimally conforming processors must support year values with a minimum of 4 digits (i.e., YYYY) and a minimum fractional second precision of 100 nanoseconds or eight digits (i.e. s.ssssssss). However, conforming processors may set larger application-defined limits on the maximum number of digits they support in these two situations, in which case those application-defined maximum numbers must be clearly documented.
