Enclosing class:
StandardPdfProducer
public class StandardPdfProducer.MarkedContentCanvas extends com.lowagie.text.pdf.PdfContentByte
Content byte that opens and closes the marked content sequences of the chunks that carry a structure element, as the text of a phrase is written.

A marked content sequence that is referenced from the structure tree has to be opened and closed in between the text showing operators of the chunks, and the PDF library offers no hook for that. Writing the operators from the generic tag page event is not an option either: the text of a column goes to a duplicate of the canvas that the column was created with and is only appended to that canvas once the whole column has been laid out, so anything written to the canvas from the event would end up before all of the text. Instead, the phrase is laid out on one of these content bytes, whose duplicate is one as well, and the text showing methods of the duplicate open the sequence of the chunk that the page event announced just before.

Consecutive chunks that carry the same structure element share a single sequence, and the sequences are closed at the end of the text object, so that they stay properly nested inside it.
