describes a single textual transposition as an ordered list of at least two pointers specifying the order in which the elements indicated should be re-combined.

The transposition recorded here indicates that the content of the element with identifier ib02 should appear before the content of the element with identifier ib01.

Transposition is usually indicated in a document by a metamark such as a wavy line or numbering.

The order in which ptr elements appear within a transpose element should correspond with the desired order, as indicated by the metamark.
