Has anyone gotten nested master pages working within MOSS I'm looking for a working example of parent & nested master page code. I've found little more than statements that they work just like ASP 2.0 master pages and this: http://msdn2.microsoft.com/en-us/library/ms476046.aspx
There is says:
For example, you can reference one master page from another master page using the following directive:
<%@ Master master=MyParent.master %>
Which isn't exactly right, because the tag needs to be "<%@ Master MasterPageFile="~sitecollection/_catalogs/masterpage/parent.master" %>
Is there a minimum set of other stuff that needs to be in a nested master page (similar to the minimum master page) to make it work
I've got my nested master pages working fine in SharePoint designer, but when I try to use them in a site, all I get is "An unexpected error has occurred. ".Thanks,
-Ryan

I fiddled with this as well but came to the conclusion that this is obviously a feature that is mentioned in a few places, it doesn't seem to be supported in SharePoint Designer, etc... If you do this, I am not sure there's much help out there or folks trying to implement this scenario...
What are you trying to accomplish Maybe there's another way...
