That makes sense.  My understanding is that I'm picking up the context of
the nodes in the for-each and comparing the first nodes of each group
matching the respective dataIds (there are multiple groups of nodes each
with a different dataId).  This may be a ambiguity or even bug, the key
reference should probably make it explicit?
