I'm working on converting Paul Austin's DataObject code to GeoTools,
so I can use it in the GPX module. (A data object is a very low-level
representation of data that SimpleFeature objects can be created
from.)

I need to describe an attribute or property of a DataObject. I was
hoping to use the GeoAPI PropertyDescriptor and PropertyType
interfaces to do this, since that is what GeoTools FeatureModel
appears to be using currently.

I'm just curious why the PropertyDescriptor and PropertyType
interfaces were made separate. How are they really different? Will
there be any issues if I implement both interfaces with a single class
providing information about a DataObject attribute?

Does GeoTools provide default implementations of these two interfaces?

Thanks for the help.
