Bug 78867 Using new registry API
Following some rework of the registry, please apply this patch to make use of the new method called getNamespace() on IConfigurationElement. This patch will convert most occurrences of: configurationElement.getDeclaringExtension().getNamespace() into configurationElement.getNamespace()

private final static String ATT_NAME = "name";
	private final static String ATT_CLASS = "class";

	private IConfigurationElement fConfigurationElement;
	public OpenTypeWizardAction(IConfigurationElement element) {
		fConfigurationElement= element;
		setText(element.getAttribute(ATT_NAME));
		
		String description= getDescriptionFromConfig(fConfigurationElement);
		setDescription(description);
		setToolTipText(description);
		setImageDescriptor(getIconFromConfig(fConfigurationElement));
