RE: Upon matching attribute value, increment output

Your title suggests you aren't thinking about the problem functionally. You
don't increment things in XSLT. What you need to do is to compute a number
that depends on the element's position.

You should be able to do this using
count(preceding-sibling::CON[(_at_)CODE=current()/@CODE]). You can also do it by
setting a variable to the current @CODE and using <xsl:number
count="CON[(_at_)CODE = $thisCode]"/>.
