If the Frame User Guide is less than clear on Text Insets, try O'Keefe and Loring (Frame 7, The Complete Reference Chapter 25, Osbourne). These two offer a lucid explanation of the role of text insets, how-why-when they should be used, alternatives to likely (but possibly mistaken) candidates for a text inset solution, and an explanation of the Xref "anomaly", with a work around using spot Xrefs. 

Pity about the workaround because it breaks a lot of accepted principles of independent fragment authoring. But there you go. It's not a perfect world and I admire, though cannot agree with, Messrs Van Dyke and Solo for their attempts to find a better solution. 

Unfortunately they may be making the same mistakes as were made years ago, when high technology was a good HB pencil, a rubber, and scissors and paste to reuse modules from other documents. Today's technology seems just to allow us to make bigger mistakes faster. 

Thanks to all contributors. This old dog did learn from the debate. And thanks especially to Thomas for the Control File idea. It's certainly a better way to go than my readme.txt files. 
Cheers
