From: Ron Bourret <rbourret@d...> > The only major difference I have found so far for XML is that the elements in > XML documents are ordered, while data members in OO programming languages are > not. There is an error in the (January 5?) XML-data report, in the very first example. It gives the clear impression that XML-data does not constrain sequence for the element types it describes. In the example, the declarations for the element types which can appear as the content of an element types are given in one order, but the instance has them in another order. (A Microsoft representative pointed this out to me: I dont know why they haven't just reissued the note, since it is a fairly cricitical point for implementors.) 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. If anyone is thinking of implementing XML-data, I suggest they befriend the authors, because the report misses out on several key issues. (I have previously mentioned that is does not seem to make clear whether you can have an XML-data schema as part of a document, or whether it must be external. If it is internal, can it describe the document's root element? I suppose a close reading of the XML-data text might help, but it is not clear to me after dozens of readings, but I do not claim to be particularly brilliant in this area.)
