Different margins in the same document

Partially.

There are two types of margin. The margin you set with the Document Inspector is global for the whole document. The Layout Margin that you set with the Layout Inspector is relative to that but can't be negative i.e. you can't make it smaller than the document margin as you said.

The bit where you were slightly incorrect is that you can adjust the layout either after a Section Break or after a Layout Break. Layout Breaks don't start on new page like Section Breaks so can be useful sometimes.

I hope that helps.

Right, except I don't think you need to set the first section to the smallest margins. Pages Help says this:

To insert a section break:
Click where you want the new section to begin.
Choose Insert > Section Break.
The new section has the same formatting as the previous section until you change it.

AppleWorks also only has section breaks which start on a new page by default, but can also start in the middle of a page. I often had problems with new sections in the middle of a page just to change the layout. I like the Pages way of separating the two functions much better.
