I'm evaluating OTRS and I'd like to know if it is possible to present
different services for my clients depending on the ticket type
selected on customer frontend (customer.pl). I've already worked on an
ACL that relates Queues and Services, but I don't know what is the
syntax to match ticket types. Remember that I want an ACL that applies
on tickets not yet created (the ACL must work when tickets are been
created). Follow the code I've tried to use, unsuccessfully.

$Self->{TicketAcl}->{'ACL-RelationTypeService1'} = {
  # match properties
  Properties => {
      Frontend => {
          Action => ['AgentTicketPhone', 'AgentTicketEmail',
'CustomerTicketMessage'],
      },
      Type=> {
          Name => ['Incident'],
      },
# I tried the options bellow too and nothing happens!
#         Ticket => {
#                Type => ['Incident'],
#         },
#         TicketType => {
#                 Name => ['Incident'],
#         },
  },
  # return possible options (white list)
  Possible => {
      Ticket => {
          Service => ['SAP System'],
      },
  },
  };
