Memory management with nibs

I have a document based app with only one window per document.

This application can open a large variety of different documents, so I
decided to create several nib files, each containing the corresponding
view for the document.

When opening the document, I check its kind and load the according nib.
This helps reduce the application footprint and the load time, as I
don't open all the nibs ...

Still, This is my first document based app and I have issues about the
files owner. For each different nib, I created a subclass of NSObject
and set it as the file owner when I load the nib with [NSBundle
loadNibNamed:] This owner has several IBOultets, but not for every
single element in the nib.

The thing is that when I release the owner, I don't think the nib is
released as well, as my nib owner is not a sub-class of
NSWindowController. But as I only have one window (that already has its
NSWindowController), I didn't wanted to use a sub-class of
NSWindowController for the nib owner.

How could I do to make sure my nib is released ?

Some "good-coding" advices would be greatly appreciated.
