The response element
Direct responses are a way to bypass C-Phrase completely on certain user questions. Responses apply immediately to user questions before pre-processing. So for example, this might help users understand that governors are not covered in the geography database.
<response from="governor" to="We do not have information on the governors of states."/>
The definition of
<!ATTLIST response from CDATA #REQUIRED to CDATA #REQUIRED alive CDATA #IMPLIED description CDATA #IMPLIED>
from is the pattern that, if matched anywhere in the input, leads to the activation of the response.
to is the exact response that is given to the user question.
