Alasdair,

Thank you very much for this feedback!

I *think* you've indeed spotted an inconsistency in the guide. If others (Richard, Keith, Jun maybe?) could have a quick sanity check as well pls ...

In general, if you (or others) find a bug or have a feature request, please feel free to use the VoID issue tracker [1] to record this - it tremendously helps us keeping track of things as well as planning for the next release.

There are currently no plans to include an inverse property of void:subset, AFAICT.

Cheers,
