  Ah yes, I remember having seen something similar in
XQueryP.  At the XQuery expression level, something like:

    try
      try-expr
    catch ( ... )
      catch-expr-1
    catch ( ... )
      catch-expr-2

  That's another approach.  On the one hand, because we are
at the expression level, that avoids the discussion on the
context (be an error in or out scope of the try).  On the
other hand, that would make some XSLT constructs untestable
within a try.

  That seems wise enough (more than ten years should have
been really long...)

  Thanks for those contextual explanations.
