If type names are global, that won't be enough to avoid conflicts.
You must avoid conflicts with all the Lisp packages that _might_ get
loaded.

It's just like the situation with function definitions and global variables.

That means you should use your package's naming convention for record
types, just as for functions and global variables, to avoid conflicts
with other packages that you don't know about.

We should document this in the Emacs Lisp Reference Manual.
