Notes
-----
The AlgorithmParameter should have a sequqnce of subelements not a choice as for Challenge/Response algorithms it MUST be possible to define both the ChallengeFormat and the Response Format at the same time. Currently the schema uses <xs:choice> which allows either <ChallengeFormat> or <ResponseFormat> but not both.
This correction will bring it in line with intended description in Section 4.3.4
