The sequence data is an ordered collection of values. It is represented by an instance of the SequenceData Class.

The elements of the sequence data are contained in the Elements Property.

The SequenceData Class is an IEnumerable of GenericData (its elements), and it has an Add Method for the same. It means that you can easily enumerate through its elements, and it can also participate in collection initializers in C# or in VB.NET.
