XML schemas Using RELAX NG

As described in the April 2005 issue of CPU - Computer Power User magazine.

This Web page provides examples related to the CPU article on RELAX NG (RNG), and also links to RNG information and tutorials. Enjoy! And if you like RNG, please remember that thanks should go the creators of that language, Murata Makato and James Clark.

A) Information about RELAX NG

This sections lists useful resources for informaton about schematron, including specifications and tutorials.

• RNG Tutorials, Specifications, and RNG-related software -- http://www.relaxng.org/.
• OASIS-related information on RNG -- http://www.oasis-open.org/committees/relax-ng/. OASIS (Organization for the Advancement of Structured Information Standards), is a not-for-profit international consortium that drives the development, convergence, and adoption of e-business standards.
• Site of ISO Committee establishing RNG as an ISO standard -- http://www.y12.doe.gov/sgml/sc34/sc34oldhome.htm.

B) Example XML File and RNG Schemas

• Example XML document -- test1.xml (plain text: test1.txt)
• Example DTD -- dtd1.dtd (plain text: dtd1.txt)
• Example RNG schema -- relax1.rng (plain text: relax1.txt)
• Second Example RNG schema -- relax1a.rng (plain text: relax1a.txt). This schema is equivalent to the previous one, but shows how RNG lets you <define> element groups, and then <ref> these groups from inside a content definition. This also introduces two new elements: <grammar> to contain the entire grammar definition, and <start> to contain the starting point (root element) for the grammar model.
