In this chapter, we've run the gamut of extension functions and extension elements, demonstrating how to add sophisticated processing power to our stylesheets. All examples have been self-contained; you could combine these functions and elements to do something really sophisticated. For example, you could use the database extension to extract live sales data from a database, and then convert it into an interactive graphic.
At this point, we've covered just about everything in the XSLT and XPath specifications. In the next chapter, we'll go through a real-world example that illustrates the full power and flexibility of using stylesheets to manipulate structured data.
