Hey Dale,
That is interesting about a legal definition, as
I've never heard of that, or seen anything in "Legalese".....and there are of course several categories of stainless steel.
The most common definition I've seen, is that a "stains" less steel contains Iron, Carbon, and a minimum of 12% Chromium.
Since you are a knifemaker you may already know this stuff, but others may possibly learn from it so, I'll take a shot...
Here is the steel chart from A. G. Russell's site...

Here is a site explaining the categories from a chemist's point of view...

And here is the Crucible Metal site...

Some knife folks are bored stiff by information like this...but maybe some others will enjoy at least some portion of it.
Besides, your post woke me up and sparked my juices this morning.
