RE: function-available() test on stylesheet functions
The assumption is that as the author of the stylesheet, you know what it contains. The idea behind use-when is that it allows you test factors external to the stylesheet itself, for example information about the XSLT processor or the environment in which it is operating. If the design required you to look at the contents of the stylesheet before deciding which parts to filter out, it would get very circular.
