Parse a date - exslt:parse-date in Saxon 6

I'm doing DocBook transformations using Saxon 6.

I have some dates in my original document in variable formats which I want to
convert to a standard format.  I would expect to do this using some sort of
parse function, then some sort of format function.

The parser will probably need a hint as to what the format is (I know it will
be one of a variety of UK formats, not US format).



I can see that a suitable parser function (parse-date) is defined in Exslt but
it isn't clear whether it is already available to me or how to get it into use
if not.  Actually according to the exslt documentation it is definitely not
available in any XSLT processor but there are JavaScript and Msxsl
implementations available.



Can someone advise how I can get this to work ?

Can I get Saxon 6 to call a JavaScript function ?



Trying it following the explanation on the Exslt site, which includes:



   <func:script implements-prefix="date"
      language="exslt:javascript"
      src="date.js" />

gives me a message "Unknown Saxon extension element: script".





Regards,

Richard.
