[rules-users] New functionality not working?

[Andrew Robinson]

Quote from the site:

Disjunctive field constraints connectives could also be used and would
not result in multiple rule generation.
      Person( eyeColour == "blue"||"green" )

Any idea on why the "from" is not correct?
      $rt: ResourceType( )
      $perm: ResourceTypePermission( accessType != AccessType.READ )
from $rt.permissions
      Role(id == $perm.role.id)

>From syntax in the docs:
