It’s quite unnecessary for you to be so condescending. Of course I’m familiar with other uses of the word. Are you? Why are you so upset by what I’ve said?

What is the distinction between a chef trained at a vocational school and a lawyer trained at a law school? Or a programmer trained at Stanford?

Chefs produce something tangible, you might say. Lawyers do, too. We draft briefs and contracts and court filings. Or maybe you’ll point out that a chef has learned a skill that takes a certain je ne sais quoi that cant be taught but can only be acquired with deliberate practice? I would say the same of programmers. (And attorneys, for that matter.) Coding is as much an art as it is a science.

And I don’t think the document you’ve linked excludes professional trades. Lawyers and doctors and programmers all provide a service:

> ‘Trade’ therefore takes its ordinary meaning, which normally involves commercial operations by a trader who provides goods or services to his or her customers in exchange for a reward.
