[alicebot-archcomm] Blank condition values

[Noel Bush]

We have said that the value of the value attribute must be a valid AIML
pattern.  An empty string is not a valid AIML pattern.  So according to
the current specification it is not possible to test for a blank value
in the ways you illustrated.  A valid way could be:

<condition name="color">
  <li value="*">Color is associated with a non-blank value.</li>
  <li>Color is associated with a blank value.</li>
</condition>
