Suppressing nodes in BizTalk mapper part deux

I wrote some post back about how to suppress nodes in BizTalk, using the graphical interface. This solution was recently under review and we had to implement some further changes to it. First I thought this could be solved in the GUI, having spent some time in there trying to fix it, I had to give up, this could not be solved using functiods or the likes. That is when I (for the second time) discovered the power of XSLT. XSLT or Extensible Stylesheet Language Transformations, is the way to go, very few limitations exist and at the end of the day, you end up with a mapping which is easier to understand and gives you a good overview, because, let’s face it, the graphical mapping in BT is anything but easy overview.
