This is a possible strategy for experimental implementation relative to
current XSLT specs, but I think that to really make the idea as useful
as possible one would have to figure out a way do define a separate
error output channel (perhaps just one of the multiple outputs allowed
in EXSLT and XSLT 2.0).  For one thing, if you thrust <error id="123"/>
into the regular output and an error template wished to handle the
exception, there is no way to pull back that error node from the output
so that it stops propagating.
