... and, if you use attributes, you can't get at them in XSL without resorting to a script. Having decided I wanted to use attributes to hold values retrieved from a database, I had to resort to writing a utility to convert attributes into child elements in order to make them accessible via XSL.
I guess this is a practical argument in favour of using elements for database values, but I'd also like to make a plea to the formulators of the XSL standard to provide a convenient way to access attributes.
Cheers, Steve.
