Ask HN: How to make professional looking technical datasheets?

What publishing tools / workflows do established electronics companies use to produce their technical datasheets? (see examples [0] [1] [2].)

The big companies each maintain their own style for text, block diagrams, timing diagrams, tabular data, and mathematical formulas across thousands of documents with numerous authors. What kind of tech are they using to enforce the style consistencies? Custom document build system? In-house SVG diagram generators? Are these kinds of tools for sale anywhere? Or would you need a print media team to polish the engineer's output according to a rigid style guide?

What kind of system could a small team adopt to be able to generate docs and graphics with this kind of brand consistency?
