Simplest possible implementation where I say "DEPRECATED" wherever I said "DRAFT" and added a "deprecated" class option.

I have one substantive comment, and a couple of nits to pick.

Substantive comment: can we avoid the term “deprecated” here? It's too vague in what it means. For example, per Wikipedia, it means “to express disapproval of (something)”; or, in technical usage “to state that a feature is deprecated is merely a recommendation against using it”. I don't think that's appropriate here. We want to say “this document is obsolete, no longer part of the baseline, and carries no authority; it is preserved for historical information only”. So given that, I'd say “obsolete” instead of “deprecated”. (I might also change the text in the “...approved as a Change-Controlled Document...” paragraph to include that “obsolete, non-baselined, historical interest only” disclaimer.)

Nits:

• The tail on the final “d” in “Deprecated” falls off the page.
• On the first page, can you get “Deprecated” to land in front of the image of the telescope? Otherwise, you get weird visual noise in the background. (Alternatively, don't print “deprecated” on the first page at all).

Reading LPM-51, suggests that the preferred term is "obsolete" rather than "deprecated".

Great minds!

...and fools.

Changed to obsolete and the suggested text added.
