comments:
tags written into the input file will be processed, but the usage of most textual entities will result in error
(use the &0000; writing, e.g. ࢮ=ࢮ)
button containing buttons may fail (not allowed by standard; firefox: an error message on reload 'failure in making a DOM element' is to be expected and no error)
the reactions of FF 2.0 ist just as expected, but:
generation of (inactive) buttons inside of buttons could be prohibited in a new release of FF, that would be correct
