@abstractmethod<EOL><INDENT>def _get_parsing_plan_for_multifile_children(self, obj_on_fs: PersistedObject, desired_type: Type[T],<EOL>logger: Logger) -> Dict[str, ParsingPlan[T]]:<DEDENT>
pass<EOL>
This method is called by the _RecursiveParsingPlan when created.
Implementing classes should return a dictionary containing a ParsingPlan for each child they plan to parse
using this framework. Note that for the files that will be parsed using a parsing library it is not necessary to
return a ParsingPlan.

In other words, implementing classes should return here everything they need for their implementation of
_parse_multifile to succeed. Indeed during parsing execution, the framework will call their _parse_multifile
method with that same dictionary as an argument (argument name is 'parsing_plan_for_children', see _BaseParser).
