Hi Frank,
I was talking with a Danish Developer a few months ago, about this very situation, albeit a different CMS.
He ended up using a numerical indexing system. It was similar to using a Table Of Contents (TOC) structure, drilling down to at least 3 or 4 layers deep.
Section 1 (index 1)
- Sub section 1 (index 1.1)
- Sub section 2 (index 1.2)
- Sub section 2, sub sub section 1 (1.2.1)
I guess it would be similar to what you see in a Word document using the H1 through to H7 header styles.
In KR's case, I guess we are looking at the Pages only - being used in a similar way.
Good luck.
George
