Re: How to restrict xsl:key

It looks as if this can be done simply by changing the match attribute to

match="Period[@domain='c']//Stamp"

Or have I misunderstood?

What changed is that the CatNumbers fall into two Periods (seedata  below).
Until today, the Catnumbers referenced always fell in Period domain='c' in my
data. They now also fall into Period domain='cr'.  I need to restrict the
output of the template to only keys built from the @domain='c' part of the
data. Have not a clue how to do this.
