[QTI] Horizontal choices in a choiceInteraction

[Niall Barr]

I think this should be achievable using the stylesheet element and class
attribute of choiceInteraction and simpleChoice. However, as the
sylesheets depends on how the player renders these elements and the
class attribute is defined as being tool-specific, this is a
tool-specific solution.

Sure. The use case here is in what the customer of our project terms
"extended matching items". That's a stimulus and a list of possible
responses enumerated with letters, so

	There follow a set of questions about leg injuries. In each case

	check the bones which may be affected.

	A	tibia
	B	patella
	C	fibula
	D	femur

And then a set of multiple response interactions, each with the same set
of options but denoted only by letter. Since the checkboxes only need a
single letter next to them, they'd like them shown horizontally. For
example

	1. Whatever the question prompt is -- can't think of one off the

	   top of my head
	[ ] A	[ ] B	[ ] C	[ ]	D

	2. Etc etc
	[ ] A	[ ] B	[ ] C	[ ]	D

Of course, the options could be fully listed each time, but this is how
the customer wants it and as such it makes sense to save vertical space
so the list of options are more likely to remain in view.
