I'm not familiar with Velocity.  I've seen it used on the IDP's views, but 
I've never written Velocity.  Is this a reasonable way to assign a default 
value:

<AttributeDefinition xsi:type="Template" id="webex_firstname">
     <Dependency ref="ONIDLDAP" />
     <AttributeEncoder xsi:type="SAML2String" name="firstname" />

     <ad:Template>
       #if( !$givenName or $givenName.isEmpty() )
         #set( $fn = "." )
       #else
         #set( $fn = $givenName )
       #end
       ${fn}
     </ad:Template>
     <ad:SourceAttribute>givenName</ad:SourceAttribute>
</AttributeDefinition>
