This sounds to me like *one* Service with two different types of Endpoint. For example a VOMS server can have voms endpoints to return credentials and voms-admin endpoints to manage VO membership, but they both talk to the same database so there is only one Service. This is the biggest structural change from GLUE 1 to 2 - in GLUE 1 there are only GlueService objects representing endpoints, but in GLUE 2 we introduced the Service concept exactly so they could be grouped together if they provide a shared functionality.
