Well, it's not actually a note, Rick, it's a submission to the W3C. But yes, the errors should be corrected, presumably by a re-submission. There are more, mostly less serious, errors and typos that should be corrected as well. > > Also note that the usage of ISO 8601 date formats seems to be wrong. > ISO 8601 date format is yyyy-mm-dd, e.g. 1998-05-09, and not 19980509, > last time I looked. Both 1998-05-09 and 19980509 are legal in ISO 8601 (there's a "full" and a "basic" format, or something like that). However, my current inclination is always to use the full form, i.e. 1998-05-09, as per Misha Wolf's and Charles Wickstead's note: http://www.w3c.org/TR/NOTE-datetime-970915.html. > > If anyone is thinking of implementing XML-data, I suggest > they befriend the > authors, because the report misses out on several key issues.

Befriending the authors is always a good idea :-), as is allowing schema information in a document instance. I think the next revision should try to define this. xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
