# Use Cases

Saxon runs all the XQuery Use Cases.

The relevant queries (some of which have been corrected from those published by W3C) are included in the Saxon distribution (folder `use-cases`) together with batch scripts for running them. A few additional use cases have been added to show features that would otherwise not be exercised. A separate script is available for running the STRONG use cases since these require Saxon-EE.

Also included in the distribution is a query `samples/query/tour.xq`. This is a query that generates a knight's tour of the chessboard. It is written as a demonstration of recursive functional programming in XQuery. It requires no input document. You need to supply a parameter on the command line indicating the square where the knight should start, for example `start=h8`. The output is an HTML document.
