| + | |||
| + | In general, a set of attributes is used to characterize a family of objects (a class); for a given object (a class instance), each "attribute" has a specific "value" that is said to be an object "property". | ||
| + | |||
| + | In the context of formal language definition, attributes are associated to grammar symbols (non-terminal, or terminal symbols) to specify the language semantics. | ||
| + | For a particular sentence in that language, the values of the set of attributes associated with the grammar axiom (or root symbol) define its specific meaning. | ||
| + | An attribute should be defined for each data item that should be known about each symbol, after the lexical and syntactical analysis of a sentence in order to do the static semantic analysis and its translation or processing. | ||
