technologies. I try to explain why SQL would not have succeeded if it had
been procedural - specifically, because it would not have enabled
implementors to compete on the strength of their optimizers.
The verbosity of XSLT is a separate question from its declarative nature.
Again, I try to explain the benefits of using an XML-based syntax (the fact
that it makes it very easy to write stylesheets that contain a lot of
boilerplate output, and the fact that it makes stylesheets amenable to
