[QTI] responseProcessing for single fill in the blank question

[Uma Abhyankar]

Hello All, 

I have following QTI 2.1 xml written for a single fill in the blank kind of question.
There could be multiple variants of a given answer and any one can be correct.

For grading such a response, I used the following responseDeclaration and
responseProcessing part. (similar to multiple response/answers type of QTI question, 
choice_multiple.xml. However in this case any one answer is correct)

After re-thinking, I am not sure, if it looks fine? I am now doubtful whether the
responseDeclaration should be different?

Part I : Single fill in the blank with multiple variants of the same answer.

Part II : Single fill in the blank with single variant of the answer. (The mapping in responseDeclaration is
--------    used to be consistent with Part I)

   </itemBody>
 <responseProcessing template="http://www.imsglobal.org/question/qti_v2p1/rptemplates/map_response"/>

Please do review both Parts and give your valuable inputs as to what should be the correct way
to write the responseDeclaration and responseProcessing parts?
