Embedded Translation
Embed output production code into the parser, so that the output is produced gradually as the parse runs.
In Syntax-Directed Translation , a pure parser merely creates an internal parse tree, so you need to do more to populate a Semantic Model .
Embedded Translation populates the Semantic Model by embedding code into the parser that populates the Semantic Model at appropriate points in the parse.
