Hi,
I have been working on a small contribution that supports the Post Schema
Validation Infoset in dom4j
I am happy to contribute this code, I have tested it with Apache Xerces
2.6.2 only, but I would appreciate some discussion :-
about the best way to package this support?
should it be part of the DOM4j behaviors? (SAXReader, BaseElement)
The changes are are simple, but a little cludgy, as I could see a way of
doing what I needed within the existing io features.
Outstanding issues
How to specify the PSVI provider in a transparent manner, the
demo forces JAXP, and makes some assumptions that may not hold true for SAX
implementations other than apache. Should there be a PSVIProvider property
for instance,
Should the SAXReader provide a capturePSVI boolean property, or
should the we use inheritance, as the demo uses
Where should be a neater way to perform the interception of the
element and attribute creation to allow for the PSVI details to be detailed.
I initially tried to use the dispatch handler, but this is package level
class, as is ElementStack etc, hence the packaging in dom4j.io
How to set the features that are required. Xerces has a number
of features that can be set. I don't know if there are standard features,
and the appropriate sets of options that will support other implementations
Test against other implementations (are there any?)
The demo requires the a.xml and a.xsd file to be in top of the C drive. (Any
non windows users will have to modifythe code in the Text.java)
There is a demo file Test.java, which can be executed, and prints out the
content of the annotation in the xsd, accessed via PSVI
I would appreciate any comments

I can sent the files but zips are being blocked from the list. I can send
then directly to anyone who is interested, orif someone can tell me of the
appropriate mechanism to package the file I will adopt that
Mike
