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/AbstractMarkersOperation.java
for (int i = 0; i < markerDescriptions.length; i++) {
					resources[i] = markerDescriptions[i].getResource();
				}
			}
		} else {
			resources = new IResource[markers.length];
			for (int i = 0; i < markers.length; i++) {
				resources[i] = markers[i].getResource();
			}
		}
		setTargetResources(resources);
	}
	/*
	 * Add undo contexts according to marker types. Any unknown marker types
	 * will cause the workspace undo context to be added.
	 * 
	 * This is an optimization that allows us to add specific undo contexts for
	 * tasks and bookmarks, without also adding the workspace undo context. Note
	 * that clients with different marker types may still assign their own
	 * specific undo context using AbstractOperation.addContext(IUndoContext) in
	 * addition to the workspace context assigned by this method.

	private void addUndoContexts() {
		String[] types = null;
		if (markers == null) {
			if (markerDescriptions != null) {
				types = new String[markerDescriptions.length];
				for (int i = 0; i < markerDescriptions.length; i++) {
					types[i] = markerDescriptions[i].getType();
