HI Greg and Bill, What I have been doing within my design standards (IPC-222X, IPC-7351) and my performance specifications (IPC-601X), is highlight areas of change within a revision with gray-shaded text. If there has been a change to a Figure or Table, then the figure or table header is gray-shaded. I will include a statement about this within section 1 of the standard, e.g., 1.7, Revision Level Changes, in IPC-6012C. This was something that my standards committees had asked of me awhile back, and it has been met with positive responses since. This is NOT a universal IPC procedure. There are other IPC standard development liaisons within IPC that DO NOT utilize this approach within revisions of standards they are responsible. I myself was trying to be responsive to those who develop and use the standards I am responsible for. I hope this helps!

But as it was explained to me the grey areas represent those items changed from the previous revision. John Perry may want to add some comments on this.

I'm assuming this is to indicate a change from previous revisions but I cannot confirm where it states this. Thanks in advance.
