The Read Only DSA Names attribute lists the AE title of each DSA
 allowed to access this DSA to perform interrogations on behalf of
 their users.

 Syntax:
 	SET DSA READ ONLY DSA NAMES {<aetitle>, ....}

 where <aetitle> is the AE title of a DSA. For example:

 	"/C=US/O=Abacus/OU=Sales/CN=DSA1"

 Refer to DSA Common_Datatypes for more information
 on how to specify an AE title.

 The default value is an empty list of AE titles, indicating
 that any DSA is allowed to interrogate this DSA (subject to other
 controls). If one or more AE titles are specified in this
 attribute, then only those DSAs are allowed to interrogate this DSA.

 Note also that the DSA refers to the value of this attribute
 whenever it receives a new connection. Once a connection is
 established, the caller is treated as a read-only DSA for as
 long as the connection lasts. Changing the value of the
 attribute has no effect on existing connections, only on
 subsequent connections.
