Hi all,

Below is some description of a combination of (RELAX NG) schema based  
validation with Schematron based validation. Maybe this is a way for us to  
"validate" the requirements which are hard to express with XML DTDs, XML  
Schema or RELAX NG.

Cheers, Felix.

at the URL:


there is available a new validating service which is able to catch much
more errors than W3C validator. Author of this service is my student
Petr Nalevka.

"Relaxed" is an easy to use HTML validation application which is special
in the sense it doesn't use the official W3C DTD's. It rather validates
HTML documents using schema definitions written in Relax NG with
embedded Schematron patterns. This is an extremely expressive
combination of languages which enables validation of additional
restrictions which can not be expressed using DTD. This includes most
restrictions specified in the W3C HTML 4.01 and the W3C XHTML 1.0
recommendation and some restrictions from WAI WCAG 1.0 Guidelines."

You can find more detailed information about implementation and source
code as well on the validator page.

Please give it a try if you are interested. This is merely protype
showing validation power of RELAX NG and Schematron running on hardware
that was new 8 years ago so please be tolerant for responses. We don't
know what this old machine will do under more serious load.
