There is no "org.apache.fop.svg.PDFDocument".
They are the following:
- PDFGraphics2D
used for drawing onto a Graphics2D into an existing pdf document, used
internally to draw the svg.
- PDFDocumentGraphics2D
used to create a pdf document and inherits from PDFGraphics2D to do the
rest of the drawing. Used by the transcoder to create a standalone pdf
document from an svg. Can be used independantly the same as any Graphics2D.
- PDFTranscoder
used to transcode an svg document into a standalone pdf, via
PDFDocumentGraphics2D.
> org.apache.batik.svggen.SVGGraphics2D
for creating an svg document by drawing into a Graphics2D.

These package and files never existed.
The files are new not old.

You do need the latest FOP at the moment, a number of important changes
have been made. You also need the current batik for proper integration.

As above. Need latest.

The main point is that the PDFGraphics2D requires the PDF creation code,
which is in FOP. Unless this code is moved I don't see why the
PDFGraphics2D should be moved.
Hopefully that has answered all you questions.
