Placement (Peach 2.2)

The placement element tell the data cracker that specific elements should be moved after the input stream is parsed. This, combined with Seek and the offset-of relation are the ways Peach supports handling files that contain references to elements by offset.

Note: Placement only works when data is being parsed into the DataModel via an input Action or a Data statement pointing to a file.
