AttributePlease note this method checks the value only - it should have the correct java binding, it should only be null if isNillable is true; and if a value is provided it should satisfy all of the restrictions provided.
To check the the number of times an attribute is used (minOccurs and maxOccurs) please use ComplexAttribute.validate().
