It would be interesting if you could turn this document into a REAL
audit checklist. Maybe you can show some samples of the types of values
that are being collected, so you can check the type of data that is
really coming through, not only the one that is supposed to be there.
Why not using regular expressions? Google Analytics use that, which
means there is already a lot of people already familiar with this
notation that helps users willing to go "beyond the basics". As a matter
of fact from what I remember Test & Target already uses regular
expressions. Can this be leveraged?
