Issue 6566: Issue: Abstract syntax tree (ocl2-rtf)
Source:  (, )
Nature: Uncategorized Issue
Severity: 
Summary: Description: Some of the elements presented in 3.3.10 (e.g. EnumLiteralExp, children of ModelPropertyCallExp) cannot be constructed without using semantic information (e.g. the type of the expression determines if a name denotes an attribute, an association end, or an operation). 
Rationale: Usually a parser produces an AST. The semantic analyser augments the AST by computing for each node from AST the values of the attached attributes. The semantic analysis also checks if there are static semantics errors and reports them. Using other terms in the AST and hence other non-terminals in 4.5 (e.g. dot-selection-expression, arrow-selection-expression, call-expression etc.) will solve this problem.
