Is PVA a 'Gum' ?

Katherine has suggested that the PVA we use as a medium for making gum prints
is not a gum.

Twenty years ago, people of a pedantic turn of mind were insisting that I was
making polyvinyl alcohol prints and not gum prints.

The reality is that PVA was developed after gum was defined as a colloidal
substance of plant origin which dissolve or wells in water. 

Now, lexicographers, being pragmatic chaps, have added to the definition:

'any substance with similar qualities'.
