-.SS Tagged and Marked PDF Content
-.PP
-Content in a page stream can be tagged to help a PDF reader application know the kind and organization of that content. Content inserted using the PDFio Page Stream Functions can be tagged by surrounding it with the pdfioContentBeginMarked and pdfioContentEndMarked functions.
-.PP
-The pdfioContentBeginMarked function accepts a named tag and optional dictionary of attributes such as the marked content identifier ("MCID"). For example, the following code tags a paragraph of text:
-.nf
-
-    pdfio_file_t   *pdf;  // PDF file
-    pdfio_stream_t *st;   // Page stream
-    
-    pdfioContentBeginMarked(st, "P", /*dict*/NULL);
-    
-    pdfioContentTextShow(st, /*unicode*/false, "Mary had a little lamb\\n");
-    pdfioContentTextShow(st, /*unicode*/false, "whose fleece was white as snow.\\n");
-    pdfioContentTextShow(st, /*unicode*/false, "And everywhere that Mary went\\n");
-    pdfioContentTextShow(st, /*unicode*/false, "the lamb was sure to go,\\n");
-    
-    pdfioContentEndMarked(st);
-.fi
-.PP
-To mark the same paragraph with a content identifier you would first create a dictionary containing the "MCID" key/value pair and then mark the paragraph with that dictionary:
-.nf
-
-    pdfio_file_t   *pdf;  // PDF file
-    pdfio_stream_t *st;   // Page stream
-    pdfio_dict_t   *dict; // Content dictionary
-    
-    dict = pdfioDictCreate(pdf);
-    pdfioDictSetNumber(dict, "MCID", 42);
-    
-    pdfioContentBeginMarked(st, "P", dict);
-    
-    pdfioContentTextShow(st, /*unicode*/false, "Mary had a little lamb\\n");

-Tagged and Marked PDF Content
------------------------------
-
-Content in a page stream can be tagged to help a PDF reader application know the
-kind and organization of that content.  Content inserted using the PDFio
-[Page Stream Functions](@) can be tagged by surrounding it with the
-[`pdfioContentBeginMarked`](@@) and [`pdfioContentEndMarked`](@@) functions.
-
-The `pdfioContentBeginMarked` function accepts a named tag and optional
-dictionary of attributes such as the marked content identifier ("MCID").  For
-example, the following code tags a paragraph of text:
-
-```c
-pdfio_file_t   *pdf;  // PDF file
-pdfio_stream_t *st;   // Page stream
-
-pdfioContentBeginMarked(st, "P", /*dict*/NULL);
-
-pdfioContentTextShow(st, /*unicode*/false, "Mary had a little lamb\n");
-pdfioContentTextShow(st, /*unicode*/false, "whose fleece was white as snow.\n");
-pdfioContentTextShow(st, /*unicode*/false, "And everywhere that Mary went\n");
-pdfioContentTextShow(st, /*unicode*/false, "the lamb was sure to go,\n");
-
-pdfioContentEndMarked(st);
-```
-
-To mark the same paragraph with a content identifier you would first create a
-dictionary containing the "MCID" key/value pair and then mark the paragraph with
-that dictionary:
-
-```c
-pdfio_file_t   *pdf;  // PDF file
-pdfio_stream_t *st;   // Page stream
-pdfio_dict_t   *dict; // Content dictionary
-
-dict = pdfioDictCreate(pdf);
-pdfioDictSetNumber(dict, "MCID", 42);
-
-pdfioContentBeginMarked(st, "P", dict);
-
-pdfioContentTextShow(st, /*unicode*/false, "Mary had a little lamb\n");
-pdfioContentTextShow(st, /*unicode*/false, "whose fleece was white as snow.\n");
-pdfioContentTextShow(st, /*unicode*/false, "And everywhere that Mary went\n");
-pdfioContentTextShow(st, /*unicode*/false, "the lamb was sure to go,\n");

-//
-// > Note: The caller is responsible for ensuring that the memory buffer is
