replace the XHTML1/HTML4 schematron schema with custom Java code
Last modified: 2013-04-20 00:00:19 CEST
Rather than dropping XHTML1/HTML4 support from the backend in order to eliminate the Schematron dependency, the current validator/schema/xhtml10/xhtml.sch file could be replaced with custom Java code similar to the Assertions.java file that we have for the HTML5 schema. Of course it still might make sense to drop XHTML1 and HTML4 from the default presets. But even so we could still keep the XHTML1/HTML4 support in the backend for third parties that want to use the validator.nu code as part of a service that provides XHTML1 and HTML4 validation along with HTML5.
