[QTI] Maximum score in a extendedText interaction

[Steve Lay]

That markup looks good to me.

normalMaximum isn't compulsory because it is possible that some 
questions won't have sensible bounds that can be expressed this way (but 
these are rare).

Setting normalMaximum is good practice I think.  Work I've done on the 
migration from QTI 1.x to 2.x supports this view as most systems have 
recorded a maximum in both the main markup and the metadata and that is 
getting translated into the normalMaximum attribute.

For guidance aimed at human scorers you could use this value to set 
controls for entering values on screen.
