7 Conclusion
</SectionTitle>
    <Paragraph position="0"> '\['his paper has discussed a number of lexical rules from recent IIPSG analyses of German (llinrichs and Nakazawa 1994) and has shown that the grammar ill some eases vastly ow~rgenerates and in other cases introduces massive spurious structural ambiguity, if lexical rules apply under unificationY ~ l\[owew'.r, no such problems of over-generation or spurious ambiguity arise, if a lexical rule applies to a giwm lexieM entry iff the lexical entry is subsumed by the. left-hand side of the lexica\[ rule. Finally we have shown that tile subsumption test for the applicability of lexical rules (;an be. integrated straightforwardly into the proposals by wm Noord and lk)mna (1994) and by Meurers and Minnen (11!)95) of how to implemeut lexical rules in a processing system for IIPSG.</Paragraph>
    <Paragraph position="1"> 13\[t is worth pointing out that the importauce of subsunlption tt~s been noted for other linguistic phenomena as well. \]hfilding proposals originating with (\]azdar et al. (1985), Bayer and Johnson (1995) ha.ve pointed out that the grammar of (cross-categorical) coordimttion for English will make the right predictions if the mother category ot7 the conjunction schema is required to subsume tile c~ttegory of ca.oh coI0un(:t. \[~y contrast, if the feb\[lion between the mother category ttnd each daughter category is that of unifialfility,'then the resulting gra.mm~tr vastly overge,erates.</Paragraph>
