XMP metadata generation from the PDFInfo object now conforms to PDF/A-1 (6.7.3 in ISO 19005-1:2005(E)).
On PDFDocument, it is now possible to set the PDF-A mode which triggers conformance checks where necessary.
The first PDF/A-1b conformance checks are now in the code. When conformance problems are detected, the new PDFConformanceException (subclass of RuntimeException since this would be a programmer error) is thrown.
PDF Renderer got a setting (through rendering options and XML configuration) to set the PDF/A-1 mode. Default is "disabled".

Initial support for XMP metadata (PDF 1.4) under fo:declarations. Both xmpmeta and RDF elements can be used as root elements for XMP metadata.
Extracted DOM2SAX functionality from XMLXMLHandler into utility class since it is now reused elsewhere.
New DOMBuilderContentHandlerFactory is used to create ContentHandlers that build generic DOMs.
New DelegatingContentHandler is a convenience base class modelled after XMLFilterImpl but as passive SAX receiver. It is used by DOMBuilderContentHandlerFactory.
Refactored FOTreeBuilder. FO tree building is now in a special ContentHandler which can be replaced temporarily when handling foreign XML like SVG or XMP. Extension Elements wanting the set their own ContentHandlers (instead of using the standard FO tree building mechanism) return a non-null value in getContentHandlerFactory(). The old mechanism is still supported (MathML, Plan and Barcode4J still use that). However, SVG support is changed to use a ContentHandlerFactory.
Extension elements for xmpmeta and RDF elements making use of the new DOM build-up using ContentHandlerFactory.
XMP metadata is passed to the renderer as ExtensionAttachment to the document. Only PDFRenderer uses the XMP extension attachment at this time.
The PDFRenderer automatically builds XMP metadata based on the basic metadata information in the PDFInfo object if no explicit XMP metadata has been added to the XSL-FO document.
XMP metadata merging is not implemented because this would involve a more sophisticated XMP infrastructure. That also means that XMP metadata is not validated. It's passed into the PDF as is.
The PDF library now provides the PDFMetadata class to embed XMP metadata in PDFs version >=1.4. stream contents use a special filter list which is initially empty, so non-PDF-aware XMP readers can extract (and optionally modify) the XMP metadata.
Trivial update:
Change the wording of a few attributeWarnings -- properties aren't ignored (possible inheritance,
property value function calls...)

Following the model of Graphics2DAdapter, added a new interface ImageAdapter which can optionally be implemented by Renderers to support painting of RenderedImage or BufferedImage instances from inside XMLHandler implementations.

Serializing both the integer and the formatted value to the area tree XML. In the XML "nr" is now "formatted-nr" and "nr" is now the integer value. This doesn't have any impact on our layout engine tests as we don't seem to use a non-default for page numbers.
Make the current PageViewport available to XMLHandler through the RenderContext.

New feature: "Intermediate format" (IF). The IF is basically the XML dialect written by the area tree renderer (XMLRenderer). A new parser for this format allows reparsing a serialized and possibly modified area tree and rendering it to the final target format. More details on the Wiki at http://wiki.apache.org/xmlgraphics-fop/AreaTreeIntermediateXml. No advanced features have been implemented, yet, only the basic functionality. The whole change should be fully backwards-compatible WRT the outer FOP API except maybe for FOTreeBuilder.addElementMapping(), and the area tree XML which got small changes.
The area tree has been cleaned up. The serializability has been restored. The CachedRenderPagesModel works again and can, in certain situations, decrease the maximum amount of memory held at one point in time. Some adjustments were necessary in the area tree to help the work of the AreaTreeParser.
The AreaTreeParser is new and is responsible for parsing area tree XML files and adding pages to a RenderPagesModel instance. It is SAX-based and should be pretty efficient.
XMLUnit (http://xmlunit.sourceforge.net, BSD license) is a new dependency for the test code. It is used to verify the correctness of the intermediate format code. It doesn't have to be installed for the build to run through, though.
ElementMapping got a new method getDOMImplementation() which provides the DOMImplementation used to handle a subdocument of a particular namespace. For example, SVG uses Batik's SVG DOM. The AreaTreeParser needs that to properly recreate foreign objects because it can't use the mechanism of the FO tree. The default implementation returns null.
The ElementMapping instances are no longer maintained by the FOTreeBuilder, but by the newly created ElementMappingRegistry class. It is expected that the instance of this class is moved from the FOTreeBuilder and the AreaTreeParser's Handler class to the "environment class" once it is created to cut down on the startup time for each processed document.
The XMLRenderer has been slightly modified to improve the serialization/deserialization qualities of the area tree XML format.
The XMLRenderer can now mimic another renderer (see mimicRenderer(Renderer)) in order to use its font setup. That way it is made certain that the reparsed area tree will render to the final target format exactly as expected.
Fixed a bug in the XMLHandlerRegistry which did not always return the right XMLHandler for every situation.
Added a DefaultErrorListener to the util package. I've had problems with Xalan-J swallowing exceptions with its default ErrorListener, so I added a simple one for convenience and use in AreaTreeParser.
Example code for working with the AreaTreeParser can be found in examples/embedding. Documentation will follow.
