ular language L of being dash-free with respect
to L and A can be read ... formalism often some sort of feature
logic serves as the constraint language to de-

precisely defined meaning. The extension we
present here, weak subsumption constraints, is
a mechanism of one-way information flow, often
proposed for a logical treatment...
