[alicebot-archcomm] <set> and unsetting them

[mehri]

The <set> in the aiml specification does not indicate what you should do whenever you hit an empty <set>.  Should that unset the variable?

For example, <set name="hello">some value</set>

<set name="hello"></set>  <!-- Unsets the value -->


Should it unset the value entirely or should it set the value to an empty string?  I saw some earlier discussions of this by searching the arch committee mailing lists.  It'd be nice if it was just put into the specification how interpreter writers should write it.
