The first PowerPoint presentation may serve as a general overview of XML schema, with the second adding more detail. SchemaXML99 is a broad and detailed overview, XSDL is a "whirlwind tour" of the eXtensible Schema Definition Language.
Schemas - Using Schemas in XML
Address Book Schema - Building a schema for the address book.
Tutorial files from W3C on Schema Documents:
Example files - Take a look through these example files. You can copy and paste sections for your final project.
Note that the examples in these chapters are almost all based on the end_species.xsd and end_species.xml files, with minor changes, according to the topic in question. More importantly, I have gone to the trouble (over two excruciating months) to flesh out the examples so that you can really play around with them, send them to XSV for validation and see how they work. Please do copy them to your own site, and then test them and retest them and analyze them. Pay special attention to the comments within the documents, in which I explain which parts are in question and what is going on with them. I hope you find them useful. Let me know.
