• decide which XML Schema validator to use

choice: Castor because it supports both code generation and class mapping, because it's open source, because it's actively developed, and because it's reasonably reviewed.

• technology:
• SAX: Simple API for XML

Does not produce representation in memory http://java.sun.com/xml/jaxb/faq.html

example validation http://www.oracle.com/technology/pub/articles/vohra_xmlschema.html

• DOM: Document Object Model

Produces in-memory representation. Validates structure but not content. http://java.sun.com/xml/jaxb/faq.html

example validation http://www.oracle.com/technology/pub/articles/vohra_xmlschema.html

• XSD: XML Schema Design validator

Does not validate parsing. http://www.oracle.com/technology/pub/articles/vohra_xmlschema.html

example validation [http://www.oracle.com/technology/pub/articles/vohra_xmlschema.html

Not clear whether creates in-memory objects. Not clear whether any easier than DOM.

• JAXB: better than SAX, DOM

Less able to handle dynamic structures. Input is XMLSchema.

• JAXP: Java API for XML Processing

Abstraction layer for XML processor independance. http://java.sun.com/xml/jaxp/reference/faqs/index.html

• xerces2-j http://xml.apache.org/xerces2-j/index.html

debian package libxerces2-java libxerces2-java-doc Supports SAX, DOM, JAXP

• msv https://msv.dev.java.net/

What the command line tools are/were using not clear it generates an in-memory image.

• Quick http://qare.sourceforge.net/web/2001-12/products/quick/index.html
