Michael,
Actually you were 100% correct. When I declared the type on the
'element' parameter I realised that I'm not passing it in this
particular call to the template. The select that was failing in
print-assertion template was only being called when the result was
false.
Cheers
Jacek

I can't see what's wrong here and I suspect the problem might be elsewhere.
One bit of advice, though: type errors are much easier to diagnose if you
declare the types of all your variables and parameters (using the "as"
attribute). This typically results in the error message being reported much
closer to the point where your code is actually wrong.
