Dear Monks,

I am building an XML template and it has been suggested that I should use XML keys instead of XML ids. The build is from the output of a relational database and therefore I suspect that it would not in theory be a problem using keys. Is there, however, a clear and easy case for conversion of ids to keys? At the moment I am using the perl module XML Simple. I won't be doing anything too advanced with those modules. I am however keen that I can justify using ids instead of keys (or the other way around).
