Technically speaking, Code2000 has many OpenType sub-tables in it.
If you look at the listing for Code2000 under the "Features" tag of the
Microsoft Font Properties tool, which Christopher Fynn mentioned,...

... you'll see that I enumerate OpenType tables in much the same fashion
as that tool.
The Font Properties Extension tool offers much useful information
about fonts installed on Windows systems. In many cases, this is
information which the font developer has added to the font in the
hope that users will be able to read it. But, without the special
tool, most users would never know...

Rudimentary contextual style tables have been added to the
working version of the font here for Latin. The official release
of Code2000 is "broken" for certain Latin letter-with-diacritic
combinations in certain string order. The working version here
seems to be, uh, working!
(I'm grateful to Bob Hallissy for pointers on this issue.)
Now that I've written programs for generating contextual
substitution tables, it is hoped that support for other scripts
needing them, like Khmer, can be improved.
