What about using fluent interfaces?:

```python
header_region = Page(some_options, ...)\
                .CSS(logout_link="a[title='Click to Logout']")\
                .CSS(user_indicator="div#page_header_div li.dropdown")\
                .CSS(user_options_button="div#page_header_div b.caret")\
                .CSS(user_options="ul#user_options_div")\
                .CSS(site_navigation_menus="div.navbar > ul > li")\
                .XPATH(something="//div/span")
```
