This branch has now landed.  Please see the rules here:

https://dev.launchpad.net/VersionThreeDotO/UI/Conversion#Heading%20rules

for what you need to change in your templates and views.  For the link  
averse:
* You will almost never need to add an H1 to your heading slot.  In  
fact, you should never need to fill your heading slot.  If you do, let  
[[mailto:barry@xxxxxxxxxxxxx|me]] know!
 * If your page is the index page for your content object, have your  
view class implement the marker interface  
`lp.app.interfaces.headings.IMajorHeadingView`.  This will put the  
root context title in an H1 above the app tabs.  Do ''not'' implement  
a `label` attribute in your view since that will add an app-colored H1  
tag below the tabs, which you don't want.
 * If your page is not the index page for your root context object,  
do nothing special.   This will put the root context title in an H2  
above the app tabs.
 * If your page is an index page and you want to allow for editing of  
the context title, have your view class implement  
`lp.app.interfaces.IEditContextTitle` instead of `IMajorHeadingView`.   
You will need to implement the `title_edit_widget` method, probably  
from the appropriate lazr-js widget, which will return the entire HTML  
(including the H1 wrapping) when called.
 * Implement a `label` property in your view class for the H1 below  
the app tabs in `LaunchpadView` subclasses.  This same property will  
be used as the form header in `LaunchpadFormView` subclasses.
 * If for some reason you do not want to use the default reversed- 
breadcrumbs in your <title>, implement the `page_title` attribute in  
your view, and set the view class attribute  
`override_title_breadcrumbs` to `True`.  Generally, you will ''not''  
want to do this, so that the default reverse-breadcrumbs are used.   
You should take the time to convert any `pagetitle.py` entries for  
your view to using a `page_title` attribute.
 * If your page template uses `CONTEXTS/fmt:pagetitle`, get rid of  
this.  Use the `base-layout.pt` and it will handle your page title for  
you.
Ping me on irc if any of the above rules are confusing or wrong.
