> This code zip is prototype for SoC 2007 project "Add support for the StAX
> (JSR-173) cursor API to Xerces-J". The code description is as follows.
> Work underway in Xerces on an implementation of JAXP 1.4. The largest
> technical change in this new edition of JAXP is the addition of StAX
> (JSR-173) which introduces XML pull parsing APIs to the Java platform. In
> constrast to push parsing APIs like SAX, StAX gives control back to the
> application at each step in the parsing process. The goal of this project is
> to design and implement the cursor-based XMLStreamReader (and filtering
> support). It should be possible to accomplish this using XNI by building the
> XMLStreamReader on top of an XMLPullParserConfiguration.
> The prototype validates the technical mechanism which builds stax parser
> based on XNI and implements intital XNI-based XMLStreamReader. The work done
> in the prototype also includes:
> * Use XMLPullConfiguration to simulate stax parsing process.
> * Implement element, attribute, text, namespacecontext, location methods.
>
> The ongoing work includes:
> * Support filter function.
> * Implement DTD, entity referrence, namespace, etc.
> * Solve the problme that XNI parsing steps do not exactly match the StAX
> steps. E.g., XNI will treat startDocument xmlDecl as two events, but StAX
> will treat as one integrated startDocument event.
