Bug 66967 [Contributions] PropertyParser should be deprecated (or removed)
Internal class org.eclipse.ui.ide/org.eclipse.ui.internal.ide.model/PropertyParser should be deprecated. People should be using the extension point org.eclipse.core.runtime.contentTypes instead Note that the tags XML_FIRST_TAG and XML_DTD_NAME have already been deprecated. Can we actually remove these instead of deprecating them?
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/internal/ide/model/PropertyParser.java
* Once we have the root level element stored, no further parsing of
         * this file is required. As a result, this method will then throw a
         * SAXException (the recommended way of aborting parsing).
         * 
         * This method is not intended to be called. It is only called from
         * within the XML SAX parser being used.
