    Determining If Functions Are Available

    In a query in a stylesheet, to determine whether the XPath processor supports a particular function, call the function-available() function. The format is

    boolean function-available(string)

    Specify a string that identifies the name of the function. The XPath processor returns true if it implements that function.
