The inconsistency about case sensitivity is almost certainly due to the 2014-07-21 update to erratum 3.15 not having being applied fully to the text: 3.15. Section 15. A new mechanism is introduced for resolving choices, to be known as ‘Direct Dispatch’, the motivation being to make the cost of resolution close to linear for choices with large numbers of branches where the branch to take is known in advance of parsing the choice. Updated by public comment 159 (http://redmine.ogf.org/boards/15/topics/159 ) to allow groups to participate in direct dispatch choice. Updated 2014-07-21 to make the match case sensitive for performance.

FYI, I noticed a handful of places in the specification that have dfdl:choiceChoiceBranchKey (with choice repeated twice).

Also, I noticed there seems to be an inconsistencty in whether or not choiceDispatchKey and choiceBranchKey are case insensitive or not. choiceDispatchKey says: The resultant string must match the dfdl:choiceBranchKey property value of one of the branches of the choice. This match is case sensitive. choiceBranchKey says: When the dfdl:choiceDispatchKey expression evaluates to a string matching this property's value, the choice is discriminated to this branch. The match is case insensitive. So choiceDispatch says the match is case sensitive, choiceBranch says the match is case insensitive.
