XML Schema Infoset Model

XML Schema Infoset Model (XSD) 

The XML Schema Infoset Model is a reference library that provides an API for use with any code that examines, creates or modifies W3C XML Schema (standalone or as part of other artifacts, such as XForms or WSDL documents).

What is XSD?

XSD is a library that provides an API for manipulating the components of an XML Schema as described by the W3C XML Schema specifications, as well as an API for manipulating the DOM-accessible representation of XML Schema as a series of XML documents, and for keeping these representations in agreement as schemas are modified.

The library will include services to serialize and deserialize XML Schema documents, and to do integrity checking of schemas (for example, not using a maximum value for a simpleType which is invalid considering the base type of that simpleType). The project goal is to support 100% of the functionality of XML schema representation, but not necessarily to provide document against schema assessment or validation services, which are normally provided by a validating parser, such as Apache's Xerces-J.
