Don't forget you don't have to just use the subsitutions for field  
values - you can change any of the text in a step. So it's pretty easy  
to negate things:

And the VAT "<caption>" <might> be present in the VAT list

Examples:
   | caption | value  |  
message                                                     |  
might      |
   | Normal  | 19.6   | VAT Normal well  
created                                     | should     |
   |         | 19.6   | You are supposed to fill the caption  
field                  | should not |
   | Normal  |        | You are supposed to fill the VAT  
field                      | should not |
   | Normal  | test   | You are supposed to fill the VAT field with a  
numeric value | should not |
