A.6 Capabilities and Options
A.4.5 Predicate Column
The item number contained in the predicate column, if any, means that the status in the
“Status” column applies only when the PICS states that one or more features identified
by the item is supported.
A.4.6 Item Reference Numbers
Each line within the PICS proforma which requires implementation details to be
entered is number at the left hand edge of the line. This numbering is included as a mean
of uniquely identifying all possible implementation details within the PICS proforma.
This referencing is used both inside the PICS proforma, and for references from other
test specification documents.
The means of referencing individual responses is done by the following sequence:
•
a reference to the smallest enclosing the relevant item;
•
a solidus character, '/';
•
the reference number of the row in which the response appears if, and only if, more
than one response occurs in the row identified by the reference number, then each
possible entry is implicitly labeled a, b, c, etc. from left to right, and this letter is
appended to the sequence.
An example of the use of this notation would be A.6.3.1.1/2, which refers to the support
for credentials in a DirectoryBind protocol data unit.
A.6 Capabilities and Options
This part of the PICS proforma identifies the supported application context, the PDUs
and operations. Finally, the operation arguments and PDU parameters are identified.
A.6.1 Supported Application Context
The only application context supported by this PICS proforma is Directory System
application context.
