language lawyering - doc strings

[gcash]

I know this is being pedantic, but where's the syntactical spec for
documentation strings in the language reference?

I was looking at the 2.1.1 docs and I'd expect it to be in "4.1 Code
blocks, execution frames, and namespaces" but the only reference to
documentation strings is where it mentions the __doc__ attribute.

I noticed this when someone asserted you can't have doc strings for
classes.
