-------------------------------------------
Resolution: Fixed
Thanks very much Wei. I've merged your initial prototype into the StAX
development branch: http://svn.apache.org/viewvc/xerces/java/branches/stax-dev.
I moved the new classes you wrote into the main org.apache.xerces.stax package
since I didn't think there needed to be a "prototype" package. The entire stax
-dev branch is essentially a development / prototyping sandbox already.

> 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.
