HTML Validation: Ability to perform custom validation for tags, attributes and attribute values in WTP ------------------------------------------------------------------------------------------------------ Key: JBIDE-18725 URL: https://issues.jboss.org/browse/JBIDE-18725 Project: Tools (JBoss Tools) Issue Type: Feature Request Components: jsp/jsf/xml/html-source-editing, upstream Reporter: Victor Rubezhny Assignee: Victor Rubezhny Labels: new_and_noteworthy Fix For: 4.4.1.GA WTP HTML validator marks any custom html tags as unknown. It's possible to disable this validation at all: Window->Preferences->Web->HTML Files->Validation ==> Set Elements -> Unknown tag name severity to "Ignore": But these days there are many frameworks provide an ability to create custom tags and attributes, so there cannot be some static schema created in order to help to validate such pages. We need to add a possibility to provide a custom validator for tags/attributes/values for WTP, so it could be called to validate a page elements.
