static final java.lang.String NET_SLP_TYPE_HINT
A value-list of service type names. In the absence of any DAs, UAs perform SA discovery for finding scopes. These SA discovery requests may contain a request for service types as an attribute.
The API implementation will use the service type names supplied by this property to discover only those SAs (and their scopes) which support the desired service type or types. For example, if net.slp.typeHint is set to "service:imap,service:pop3" then SA discovery requests will include the search filter:
(|(service-type=service:imap)(service-type=service:pop3))
The API library can also use unicast to contact the discovered SAs for subsequent requests for these service types, to optimize network access.

Active and passive DA discovery or SA discovery are used for scope discovery, and the scope "DEFAULT" is used if no other information is available.
If a DA or SA gets another scope in a request, a SCOPE_NOT_SUPPORTED error should be returned, unless the request was multicast, in which case it should be dropped. If a DA gets another scope in a registration, a SCOPE_NOT_SUPPORTED error must be returned.- See Also:
