/**
 * Presentation text data contains the graphic characters and the control
 * sequences necessary to position the characters within the object space. The
 * data consists of: - graphic characters to be presented - control sequences
 * that position them - modal control sequences that adjust the positions by
 * small amounts - other functions causing text to be presented with differences
 * in appearance.
 * <p>
 * The graphic characters are expected to conform to a coded font representation
 * so that they can be translated from the code point in the object data to the
 * character in the coded font. The units of measure for linear displacements
 * are derived from the PresentationTextDescriptor or from the hierarchical
 * defaults.
 * <p>
 * In addition to graphic character code points, Presentation Text data can
 * contain embedded control sequences. These are strings of two or more bytes
 * which signal an alternate mode of processing for the content of the current
 * Presentation Text data.
 * <p>
 * The content for this object can be created using {@link org.apache.fop.afp.ptoca.PtocaBuilder}.
