 * Extends the original concept of a document partitioner to answer the position
 * categories that are used to manage the partitioning information.
 * <p>

 * A delimited partition has a predefined textual token delimiting its start and
 * end, while an open partition can fill any space between two delimited
 * partitions.
 * </p>
 * <p>
 * An open partition of length zero can occur between two delimited partitions,
 * thus having the same offset as the following delimited partition. The
 * document start and end are considered to be delimiters of open partitions,
 * i.e. there may be a zero-length partition between the document start and a
 * delimited partition starting at offset 0.
