Search result icons in Xcode?

Question

I'm looking for info on the icons displayed in search results in Xcode.

The meaning of some icons is obvious, I think.

M = Method, C = Class, S = Struct, Pr = Protocol, etc. But others are not so obvious.

What do you call these icons in the Xcode help listing ?
Is there a "legend" that describes these icons ?

I've tried searching but I'm at a loss what to call these icons.

I can provide a pic if necessary, but can't post one.

Answer 1

Can't find any help about them either but with find-fu I think found them in /Developer/Library/PrivateFrameworks/DVTFoundation.framework/Versions/A/Resources named Xcode.SourceCodeSymbolKind.Category.Icon.pdf etc.

Update: Did some Inkscape and HTML fiddling and generated this image:
