Subject: Re: To get things started.... Data formats
Betty, > The @ and the $ are not valid name characters in XML so they cannot > be used in either element or attribute names. Yes they can. XML can be made to do anything you want with it. That's why it's called "extensible", because it can be extended. It's a flexible technology that is able to adapt to modern business needs. If you think the technology is static, then you should remember that in the old days, people said that you couldn't sail too far out to sea or you'd fall off the end of the earth. I do admit we are stretching the bounds of XML and make no apology for it. Actually the '$', '@', '#', '?' specifiers don't form part of the element name as you say they do. They simply denote the type of data that is stored so that the values can be safely read and converted to a different data-type if that is neccessary. Hence, Transaction_Amount can be expressed either as Transaction_Amount&="34.56" (a string), or as Transaction_Amount$=34.56 (a currency field). They're both talking about the same data element, which is Transaction_Amount. Thanks for your comments in any case.
