StringExpression
```
public interface Expression
extends ValueSpecification
```
A representation of the model object 'Expression'. An expression is a structured tree of symbols that denotes a (possibly empty) set of values when evaluated in a context. An expression represents a node in an expression tree, which may be non-terminal or terminal. It defines a symbol, and has a possibly empty sequence of operands which are value specifications.
The following features are supported:
- Symbol
- Operand
