-/**
- * <P>Primary class that drives overall FOP process.
- *
- * <P>Once this class is instantiated, methods are called to set the
- * Renderer to use, the (possibly multiple) ElementMapping(s) to
- * use and the PrintWriter to use to output the results of the
- * rendering (where applicable). In the case of the Renderer and
- * ElementMapping(s), the Driver may be supplied either with the
- * object itself, or the name of the class, in which case Driver will
- * instantiate the class itself. The advantage of the latter is it
- * enables runtime determination of Renderer and ElementMapping(s).
- *
- * <P>Once the Driver is set up, the buildFOTree method
- * is called. Depending on whether DOM or SAX is being used, the
- * invocation of the method is either buildFOTree(Document) or
- * buildFOTree(Parser, InputSource) respectively.
- *
- * <P>A third possibility may be used to build the FO Tree, namely
- * calling getDocumentHandler() and firing the SAX events yourself.
- *
- * <P>Once the FO Tree is built, the format() and render() methods may be
- * called in that order.
- *
- * <P>Here is an example use of Driver from CommandLine.java:
- *
- * <PRE>
- * Driver driver = new Driver();
- * driver.setRenderer("org.apache.fop.render.pdf.PDFRenderer", version);
- * driver.addElementMapping("org.apache.fop.fo.StandardElementMapping");
- * driver.addElementMapping("org.apache.fop.svg.SVGElementMapping");
- * driver.setWriter(new PrintWriter(new FileWriter(args[1])));
- * driver.buildFOTree(parser, fileInputSource(args[0]));
- * driver.format();
- * driver.render();

- Modified by Mark Lillywhite mark-fop@inomial.com. The changes
- here are based on memory profiling and do not change functionality.
- Essentially, the Block object had a pointer to a BlockArea object
- that it created. The BlockArea was not referenced after the Block
- was finished except to determine the size of the BlockArea, however
- a reference to the BlockArea was maintained and this caused a lot of
- GC problems, and was a major reason for FOP memory leaks. So,
- the reference to BlockArea was made local, the required information
- is now stored (instead of a reference to the complex BlockArea object)
- and it appears that there are a lot of changes in this file, in fact
- there are only a few sematic changes; mostly I just got rid of
- "this." from blockArea since BlockArea is now local.

-/**
- * 6.6.11 fo:page-number-citation
- *
- * Common Usage:
- * The fo:page-number-citation is used to reference the page-number for the page containing the first normal area returned by
- * the cited formatting object.
- *
- * NOTE:
- * It may be used to provide the page-numbers in the table of contents, cross-references, and index entries.
- *
- * Areas:
- * The fo:page-number-citation formatting object generates and returns a single normal inline-area.
- * Constraints:
- *
- * The cited page-number is the number of the page containing, as a descendant, the first normal area returned by the
- * formatting object with an id trait matching the ref-id trait of the fo:page-number-citation (the referenced formatting
- * object).
- *
- * The cited page-number string is obtained by converting the cited page-number in accordance with the number to string
- * conversion properties specified on the ancestor fo:page-sequence of the referenced formatting object.
- *
- * The child areas of the generated inline-area are the same as the result of formatting a result-tree fragment consisting of
- * fo:character flow objects; one for each character in the cited page-number string and with only the "character" property
- * specified.
- *
- * Contents:
- *
- * EMPTY
- *
- * The following properties apply to this formatting object:
- *
- * [7.3 Common Accessibility Properties]
- * [7.5 Common Aural Properties]
- * [7.6 Common Border, Padding, and Background Properties]
- * [7.7 Common Font Properties]
- * [7.10 Common Margin Properties-Inline]
- * [7.11.1 "alignment-adjust"]
- * [7.11.2 "baseline-identifier"]
- * [7.11.3 "baseline-shift"]
- * [7.11.5 "dominant-baseline"]
- * [7.36.2 "id"]
- * [7.17.4 "keep-with-next"]
- * [7.17.5 "keep-with-previous"]
- * [7.14.2 "letter-spacing"]
- * [7.13.4 "line-height"]
- * [7.13.5 "line-height-shift-adjustment"]
- * [7.36.5 "ref-id"]
- * [7.18.4 "relative-position"]
- * [7.36.6 "score-spaces"]
- * [7.14.4 "text-decoration"]
