I just discoverd errors in my book-description under point 3. Sorry, I
didn't test the grammar. Now it really works. As an additional
explanation: SKIP recognizes all text up to the tokens, which can
follow on SKIP


The first improvement should be:


Book ::= SKIP? Chapter+


Chapter ::= TITLE SKIP


TITLE ::= \d\.[^\r\n]+ // as example, if you take the guide text as a
book




After the second improvement, the grammar would be


Book ::= SKIP? Chapter+


Chapter ::= TITLE Paragraph+


Paragraph ::= EOL+ SKIP


TITLE ::= \d\.[^\r\n]+
