| Abstract |
|
This paper presents an approach to the specification
of visual language syntax. Based on attributed graphs
as the notion of abstract syntax, syntactical correctness
is specified by a set of predicates over that structure.
The proposed technique facilitates the natural embedding of other visual and textual notations, the definition
of complex syntactic and static-semantic properties, as
well as precise error diagnosis and localization. An
editing environment supporting this technique is briefly
discussed.
