The definition of the dateTime value space does not reference a part of ISO 8601 that defines dateTime values, only lexical representations. The reference should be corrected, and the recommendation should explain or fix the fuzziness and/or gaps in the definitions referenced. Dave P: "In 3.2.7 we assert that "the value space of dateTime is the space of Conbinations of date and time of day values as defined in [Clause] 5.4 of ISO 8601". I notice also that Clause 5 of 8601 is titled "Representations" and the first sentence of Clause 5.4 asserts "a time-point can be identified through a combination of date and time of the day representations provided for in this International Standard". From this, I conclude our reference is at best incorrect, since the referenced text only addresses standardized lexical representations." "It is clear from our discussions that we do not equate dateTime values with lexical representations thereof; the mapping is not 1-1."
