The Service Location Protocol Service Scope Option specifies two
things: a list of service scopes for SLP, and whether the use of this
list is mandatory. If the initial boolean value is true, the SLP
agent should only use the list of scopes provided in this option;
otherwise, it may use its own static configuration in preference to
the list provided in this option.
The text string should be a comma-seperated list of scopes that the
SLP agent should use. It may be omitted, in which case the SLP Agent
will use the aggregated list of scopes of all directory agents known
to the SLP agent.
