I'm a lawyer. Could you help me examine the question how to achieve referential integrity of a document.

For example:

Section 1.1(a)(viii) of the Seller Disclosure Letter is hereby amended by adding a new item 12 thereunder as follows: Agreement, dated as of March 1, 1994, between Behringwerke AG and Immunex Corporation.

If I change the number of the section 1.1. into 1.5 I want to have it automatically changed all over the document.

Is it possible in MS Word?
