Ops, ok, I see... thanks, I now have tried (also) that syntax... but to no avail. Screenshot of some TV's I'm trying to catch:

That is, I don't get the expected printout from the template using the following expression:
%attTab:"AllowNULL"%Are there any Tools or something such that also needs to be included in the "path" or identifier of the TV?
Edit: This code is in the template named "Attribute Declaration" so the context for the TV should be ok.
