January 2007 - The beta implementation of ISO Schematron is now available. This XSLT-based implementation is the successor to the Schematron 1.5 stylesheets in wide-spread use (and follows the same "meta-stylesheet" design pattern.) It implements almost all ISO Schematron (only abstract patterns are yet to be implemented) and is the result of collating years of suggested improvements from Schematron users; an implementation status document is available. The implementation is structured as a "skeleton" that allows output functions to be overridden by customized validators; basic API documentation is available.
January 2007 - Accompanying the beta release of ISO Schematron skeleton is several validators that produce customised output. Schematron Terminator is a validator that halts with an error code when the first error is detected. Schematron SVRL is a validator that generates Schematron Validator Report Language XML documents, which are specified by the ISO Schematron standard. Notes on the page detail a technique for using a Schematron schema to test SVRL documents, and on how the new flag attributes can be used.
January 2007 - ISO SVRL (Schematron Validation Report Language) implementation now available from this site. SVRL is an XML language to present the results of validating with a Schematron schema.
