[vtkusers] what about a vtkStringArray format ?

vtkDataArray is not really the right superclass for an array
of strings. It has a lot of methods which make no sense in
an array of strings. Furthermore, it is not possible to implement
things such as interpolation for strings. I think it would be more
cleaner to associate some sort of standard container of strings (an
STL vector?) with your dataset.
