How to add custom actions to the Settings page for a Document Library?

Question

I want to add a custom action under General Settings on the Document Library Settings page (listedit.aspx). So I added a new SharePoint 2010 "Empty Element", and put this code in the Elements.xml file:
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<CustomAction
Id="MyClassName"
Sequence="999"
GroupId="GeneralSettings"
Location="Microsoft.SharePoint.ListEdit.DocumentLibrary"
Title="My Link"
Description="My description here"
Rights="ManageWeb">
<UrlAction
Url="~sitecollection/_layouts/MyProject/MyPage.aspx"/>
</CustomAction>
</Elements>
I found the GroupId and Location here: http://msdn.microsoft.com/en-us/library/bb802730.aspx but I am starting to wonder if this documentation is for MOSS2007 rather that SP2010
as it says.
What am I missing?
Any help or hint would be greatly appreciated!

Hi Henrik,
Can we add above custom action in our custom group like General Settings?
I have tried for that but it is not working.
I have tried as follows
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<CustomActionGroup
Id="LibrarySettings.MyGroup"
Title ="My Group"
Sequence="1000"
Location="Microsoft.SharePoint.ListEdit">
</CustomActionGroup>
<CustomAction Id="Custom.Configuration.ListCustomSettings"
GroupId="LibrarySettings.MyGroup"
Location="Microsoft.SharePoint.ListEdit"
RequireSiteAdministrator="FALSE"
Sequence="100"
Title="Library Admins">
<UrlAction Url="_layouts/15/LibrarySettings.aspx?List={ListId}" />
</CustomAction>
</Elements>
But custom group is not created in list settings
Any idea what I am missing here?
