Sure - I understand there's no concept of time in the evaluation of a transform but there certainly is for me sat in my chair waiting for it to finish :) I often do: <xsl:if test="position() mod 1000 eq 0"> <xsl:message select="concat('Processed ', position(), '/', $total')"/> to output: Processed 1000/1000000 Processed 2000/1000000 ... which is good enough to show something is happening but it would've been nicer to also show an estimated finish time based on progress so far. I wrongly thought that the "implementation dependent" part meant the processor could return different values for multiple calls to current-dateTime()... instead of merely the freedom to choose the instant at which it takes the fixed value. It should be straightforward to write an extension function instead... -- Andrew Welch http://andrewjwelch.com Kernow: http://kernowforsaxon.sf.net/
