Similarly, the value of the Seconds component allows an arbitrary decimal." What exactly is the lexical form of arbitrary integer and arbitrary decimal? Does it mean the lexical form of the "decimal" and "integer" datatypes as defined in section 3.2.3 and 3.3.13? Apparently not since it says "P-1347M" is not allowed even though "-1347" is a perfectly good integer. If not, what does it mean? Specifically, which of the following are allowed? (a) P+1Y (b) P-1Y (c) P-0Y (d) P.1S (e) P1.S ISO 8601 allows only a sequence of digits, but since ISO 8601 is not cited normatively a reader cannot rely on that. The provision of fractional sections goes beyond what ISO 8601:1988 allows. However, according to my (draft and thus perhaps no longer correct) copy, ISO 8601:2000 does not allow any of (d) or (e) (even though they are valid instances of the XML Schema decimal data type).
