           Summary: R-118: Questions about the value space for dateTime
           Product: XML Schema
           Version: 1.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSD Part 2: Datatypes

1. The Datatypes spec states that "The value space of dateTime is the space of 
Combinations of date and time of day values as defined in 5.4 of [ISO 8601]." 
The implication of this is that 2002-02-02T12:00:00Z is a distinct value in the 
value space from 2002-02-02T07:00:00-05:00. But if this is so, then the 
canonical lexical representation (which is always in UTC with timezone 
designator Z) cannot represent all values in the value space. 
2. The description of the value space could also be read as indicating that 
12:00:00Z and 12:00:00+00:00 are distinct values, and that the year 02002 is 
distinct from the year 2002.
