This comment appears in draft 034 with respect to leading/trailing skip bytes. Since I am in there fixing up the grammar and associated pictures I'd like to fix this also if a change is needed. Unfortunately, MS Word change tracking says this comment is by "Lab User" ... so I have no idea who said this, but I assume it's an IBMer.
In our MRM model, for repeating element we state that a leading skipCount applies only to first occurrence of array element and trailing skipCount applies to all elements of the array. The model in that sense is not symmetrical. I thinking if we should model this properly for array where we state that an array construct as such has a prefix Region and suffix Region which carry these alignment attributes.
