The main change is to introduce the possibility to use disjunctions on
identifiers,
such as function names, structure field names, local variable names, etc.

The choice operator can be used in more situations now.
I would like to clarify if this feature can also be used for the filtering of
comments and string initialisations with the semantic patch language.
I find that another interesting aspect is the handling of whitespace characters
in this context.
- A couple of programming languages do not allow their use in identifiers while
they are fine in some other places of the source code.
Can such special characters be enclosed by a selection element?
- How does the SmPL grammar distinguish the places where it is acceptable to add
whitespaces between selection elements optionally?

Markus
