In HPSG the grammar consist of a type hierarchy and a set of principIes. In fact, principIes of the grammar (induding ID Schemata) are constraints over featu re structures and can easily be expressed as so. With this, HPSG manages to model alllinguistic knowledge in terms of typed feature structures without resorting to principIes or rules. Inheritance and Lexical Rules (LR) allow to eliminate redundancy. Broadly speaking, inheritance avoids 'vertical' redundancy and LR avoid 'horizontal' redundancy. LRs, however, are not part of the formalism, they are not typed and fall outside the linguistic taxonomy. In this paper we investigate ways of expressing the generalization power of LRs without using LRs. We integrate LRs as feature structures using disjunction and simulating dosure operator by means of the inheritance mechanism of the hierarchy itself. We can express LRs generalizations using new types with extended feature structures and modified inheritance mechanisms allowing for disjunctive inheritance. This allow to homogenize linguistic knowledge representation.
