[Data-modeling] Removing included type from a type?

[Philip Kendall]

Hopefully an easy one...

I've created a "computer peripheral" type[1], which I did as part of the ZX
Spectrum base as a place to test it. The type now has an included type of
/base/zxspectrum/topic which I can't seem to remove by the UI, and which is a
slight problem as the type is now being used for some non-Spectrum peripherals.
Is there a way to remove this type, either via the UI or more directly?

Cheers,

Phil
