[Acegisecurity-developer] In the Acegi config xml file why use /A and /Z in the URL pattern?

[Garvey, Paul M (GE Comm Fin)]

In the following snippet below why are /A and /Z used in the URL? For
example " \A/c/portal/login\Z"?
Why not remove the /A and /Z to leave  "/c/portal/login"?
 
 
 <bean id="filterInvocationInterceptor"
class="org.acegisecurity.intercept.web.FilterSecurityInterceptor">
  <property name="authenticationManager" ref="authenticationManager" />

  <property name="accessDecisionManager" ref="accessDecisionManager" /> 
  <property name="objectDefinitionSource">
   <value>
            PATTERN_TYPE_APACHE_ANT
            \A/c/portal/login\Z=ROLE_AUTHENTICATED
            \A/c/portal/logout\Z=ROLE_AUTHENTICATED
            \A/c/portal/layout.*\Z=ROLE_AUTHENTICATED
            \A/group/.*\Z=ROLE_AUTHENTICATED    
   </value>
  </property>
 </bean>
