• Thread-topic: Question regarding PSVI..

Appendix C2 of the W3C XML Schema recommendation describes the
contributions to the Post-Schema-Validation Infoset (PSVI). Which are
basicaly additions to an XML document's infoset made after it has been
validated. 

http://www.w3.org/TR/xmlschema-1/#outcomes

IBM's proposal describes requirements for an API for manipulating W3C
XML Schema components which is not related. 

PS: To properly describe the PSVI for your document, I'd need an
actually schema with targetNamespaces, defaults, schema locations and
the whole hog.

This seems to provide an interface for querying and modifying XML
Schema.

Post Schema Validation Infoset - I did not really find information
regarding this. I am looking for a short tutorial for this, such as
where they expect this will be used, and also how PSVI works.

For example, let us consider a simple schema to see how PSVI works.

Book -> book (Title)
Title -> title (String)

and the document

<book><title>Intro to XML</title></book>

what is the PSVI for the above document?

thanks and regards - murali.
