It all depends on whether you can recognize where such sections start and end. If you want to ignore them, you can basically treat them as comments. That means that if you can come up with a terminal rule to recognize such sections then you can expand the comments terminal rule to include that new rule. Alternatively, you can have an attribute in a type rule which "parses away" the whole section -that way the whole section will be in the model (as a long String), but you can choose not to do anything more with it.
