Summary: 'results from' is a relation used to tie a conferred quality
to a process. Conferred qualities have been obsoleted from OBI, and
defined classes created instead such as 'digested material' which is
the specified output of a 'digestion process'. The relation is
therefore no longer used, is undefined in the file, and creates the
danger of being used accidentally for something else (has happened; I
myself thought it was to indicate causality between processes).
