Remarks

A code element can be any fragment of code, but generally, there is a CodeElement2 object for each definition or declarative syntax in a language. This means that for most top-level definitions or declarations in a file, or for any syntactic form in a class definition, and so forth, there is a corresponding CodeElement2 object.
