This chapter described the functions that are added to the core library by the XSLT specification. Information about the functions provided by XPath 2.0 is available in XPath 2.0 Programmer's Reference .
This chapter brings the reference part of this book to a close. You now have what I hope is a definitive reference guide to the XSLT language. The following chapters are designed to help you put the language to work, developing real-world applications. In Chapter 8, we look at the rules for writing XSLT extension functions.
