Bug 173902 remove EXPERIMENTAL markings from 3.3 IDE Undo API
Need to remove the EXPERIMENTAL javadoc from the new API I introduced in 3.3. See org.eclipse.ui.ide.undo org.eclipse.jface.fieldassist
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/ide/undo/AbstractWorkspaceOperation.java
modelProviderIds = ids;

	/**
	 * Set the resources which are affected by this operation
	 * 
	 * @param resources
	 *            an array of resources
	 */
	protected void setTargetResources(IResource[] resources) {
		this.resources = resources;
	}
	/**
	 * Return the workspace manipulated by this operation.
	 * 
	 * @return the IWorkspace used by this operation.
	 */
	protected IWorkspace getWorkspace() {
		return ResourcesPlugin.getWorkspace();
	}
	/**
	 * Return the workspace rule factory associated with this operation.
	 * 
	 * @return the IResourceRuleFactory associated with this operation.
	 */
	protected IResourceRuleFactory getWorkspaceRuleFactory() {
		return getWorkspace().getRuleFactory();
	}
	/**
	 * Mark this operation invalid due to some external change. May be used by
	 * subclasses.
