[Lazarus] Can I delete a property from a collectionitem

[nibbikfrans]

Hi,

I have a collection stored in a file. One property of each 
collectionitem is a value of what seeems to be a set but is not. That 
property is no longer needed. Is there a way to delete that property? I 
suppose I can do that by creating a new collectionitem type without that 
property and migrate the data. But then a have a different collection 
which meens a have to make lots of changes.
If deleting a property isn't possible, how can I delete the value of 
that property?

And an extra question is: how can I test whether the property has a 
value or not?

The possible value is defined as followes:
TTest = (test1, test2, test3);
TTestValues = set ot TTest;
