## Package com.icl.saxon.functions Description

This package provides implementations of all the supplied functions for use in XPath expressions.

There is one class for each standard (XSLT or XPath defined) function. These all inherit from the class com.icl.saxon.expr.Function.

There is also a class Extensions which implements SAXON-defined extension functions. This contains one method for each extension function.
