Sidestepping David And Mike's comments for the minute:

The rationale here, 'Java is better than XSLT', is something I would
argue with. That is probably fine for Jeni T, I don't think it is 
right to say it is 'best' for everybody.
  
I don't think I want to take this any further until the DC comment
re ns is resolved.

To my way of thinking the 'end user' here is the stylesheet author,
not the recipient of the styled source file.

Which is why I want to wait for the ns resolution (say's he,
chickening out v.quickly :-)

Though there are probably stylesheet author reasons why, say,
the exslt:something or other isn't quite right for him/her,
perhaps the date formatting isn't right for my locale?
