Good.

Thank you for your notes. Actually I do use cl-yacc and cl-lexer on  
earlier version, and soon find too many conflicts which cannot shift  
by cl-yacc and then turn to ZEBU.

There's a ASN.1 Book which talk about the parse of ASN.1:

http://www.oss.com/asn1/dubuisson.html

In this book, author said the ASN.1 BNF, when using a LALR parser, can  
produce hundred of conflicts. And this book suggest that, to parse  
full ASN.1, LALR parser isn't fit to use. Maybe LL parser is better.

I'm still reading this book. I decide to finish reading first, then  
continue to think about my ASN.1 parse job. I think I need more  
knowledge of ASN.1, it's quite complex.
