Error text: invalid format specification '___'
DISPLAY-HINTs are not allowed for TC's with SYNTAX of OBJECT
IDENTIFIER, IpAddress, Counter32, Counter64, or any enumerated
syntax (BITS or INTEGER).
Formats for INTEGER, Integer32, Unsigned32:
The first part is a single character suggesting a display format,
either: `x' for hexadecimal, or `d' for decimal, or `o' for octal, or
`b' for binary. For all types, when rendering the value, leading
zeros are omitted, and for negative values, a minus sign is rendered
immediately before the digits. The second part is always omitted for
`x', `o' and `b', and need not be present for `d'. If present, the
second part starts with a hyphen and is followed by a decimal number,
which defines the implied decimal point when rendering the value.
Formats for OCTET STRING:
The hint consists of one or more octet-format specifications. Each
specification consists of five parts, with each part using and
removing zero or more of the next octets from the value and producing
the next zero or more characters to be displayed. The octets within
the value are processed in order of significance, most significant
first.
The five parts of a octet-format specification are:
(1) the (optional) repeat indicator; if present, this part is a `*',
and indicates that the current octet of the value is to be used as
the repeat count. The repeat count is an unsigned integer (which
may be zero) which specifies how many times the remainder of this
octet-format specification should be successively applied. If the
repeat indicator is not present, the repeat count is one.
(2) the octet length: one or more decimal digits specifying the number
of octets of the value to be used and formatted by this octet-
specification. Note that the octet length can be zero. If less
than this number of octets remain in the value, then the lesser
number of octets are used.
(3) the display format, either: `x' for hexadecimal, `d' for decimal,
`o' for octal, `a' for ascii, or `t' for UTF-8. If the octet
length part is greater than one, and the display format part refers
to a numeric format, then network-byte ordering (big-endian
encoding) is used interpreting the octets in the value. The octets
processed by the `t' display format do not necessarily form an
integral number of UTF-8 characters. Trailing octets which do not
form a valid UTF-8 encoded character are discarded.
(4) the (optional) display separator character; if present, this part
is a single character which is produced for display after each
application of this octet-specification; however, this character is
not produced for display if it would be immediately followed by the
display of the repeat terminator character for this octet-
specification. This character can be any character other than a
decimal digit and a `*'.
(5) the (optional) repeat terminator character, which can be present
only if the display separator character is present and this octet-
specification begins with a repeat indicator; if present, this part
is a single character which is produced after all the zero or more
repeated applications (as given by the repeat count) of this
octet-specification. This character can be any character other
than a decimal digit and a `*'.
Output of a display separator character or a repeat terminator
character is suppressed if it would occur as the last character of
the display.
If the octets of the value are exhausted before all the octet-format
specification have been used, then the excess specifications are
ignored. If additional octets remain in the value after interpreting
all the octet-format specifications, then the last octet-format
specification is re-interpreted to process the additional octets,
until no octets remain in the value.
