An LD-rule X <math>\rightarrow</math> <math>Y_1,</math> <math>Y_2,</math> ..., <math>Y_n </math> is interpreted as a well-formedness condition for local trees: It licenses all local trees with a root X and daughters <math>Y_1,</math> <math>Y_2,</math> ..., <math>Y_n </math>. The order of the daughters dominated by X is considered to be irrelevant.

LD-rules were first introduced in Generalized Phrase Structure Grammar.
Formally, the righthand side of an ID-rule can be considered as a multi sets.
