Feature specification defaults

Feature specification defaults (FSDs) are a device used in Generalized Phrase Structure Grammar to specify values for those features of a category which are not determined by any other module of the grammar (ID-rule, lexicon entry, Feature instantiation principles, etc.).

Example

FSD 7: [BAR 0] <math>\rightarrow</math> <math>\neg</math>[VFORM PAS] The feature specification [VFORM PAS] (verb form = passive participle) will not be freely instantiated in any lexical category; i.e. it has to be licenced by an ID-rule or an lexical entry.

Comments

Like Feature cooccurrence restrictions, most FSDs can be considered as implications.
