I noted that the TextualAttributeType implements four (4) different interfaces and three (3) classes in its ancestry, not counting Object. So I think I'll need to do a little flow chart so I can understand how everything relates. :]
Then I'll decide what GeoTools class I need. I now believe it exists, but I just have to find it. Landon P.S. - I really like the GeoAPI Filter interface used by GeoTools. Slick design.
