This is indeed still possible, because it is not handled by pass 2, but
by wml itself.  In few words, an asterisk is allowed in tag name, so
even if <table> is defined, <table*> is not (until specifically
redefined) and asterisks are removed after pass 2.

Yeap, great idea.

Sure, everyone agrees that WML is too simple, having different
behaviours depending on some command line options will make WML more
spicey ;-)

But <br> is a simple tag, so <br/> is sufficient ;-)

Here is the proposed syntax for parsing unknown tags:
- they are complex by default
- when there is a trailing slash or when tag name ends with an asterisk, 
  it is a simple tag

Sounds good.
