Suggest a different name to indicate this is more of a fragment from a the
same parent (e.g. fragment.parent.identifier or fragment.group.identifier)? To
me using fragment alone implies a unique id for that split instance (even
though I know the attribute description explains more)

> Some "splitting" processors such as SplitText and SplitContent write
> attributes to the split flow files indicating their fragment index, the total
> count, and the filename of the original flow file. This is done to support a
> form of "micro-batching" and/or a split-join pattern in a data flow (i.e.
> split the original file, do work on the individual pieces, and possibly merge
> them together later).
> For consistency and capability, the SplitJson and SplitXml processors should
> write these same attributes for their split flow files.
