Hi All:
Can any one explain the relationship and difference between the abstract
syntax and concrete syntax? I'm always confused about these two terms when
reading the UML and related specification.

I think the concrete syntax is corresponding to the syntax that defined by
EBNF. And I can also understand in UML, abstract syntax is corresponding to
the abstract concepts and relationships used in UML. but I don't know how to
put these two together.

Thank a lot.
