<td colspan="5" class="print">0008009: Missing rule for no optional
attribute (or default value of the optional attribute)</td>
</tr>
<tr class="even print">
<td class="print-category">Description</td>
<td colspan="5" class="print">TTCN-3 core language standard defines no
implicit value of the optional attribute. The rules are usually composed
in such a way that there are common basic rules that always apply and
then specific rules for cases when either "explicit omit" or "implicit
omit" is defined. E.g. rules on list notation of record values defined
in 6.2.1.0 say that "Fields not mentioned are implicitly left
uninitialized." This is followed by rules for "explicit omit" which
basically say the same and rules for "implicit omit" that define a
different behaviour.<br />
<br />
Unfortunately, this is not always the case. E.g. rules for expansion of
record values defined in 6.2.1.1.a have only two alternatives: one for
"explicit omit" and the other for "implicit omit". With no default value
of the optional attribute it is unclear what should happen in this case.
Our tool has always used "explicit omit" for these cases, but we have
recently encountered a situation when the testing environment was made
in other tool which used "implicit omit".<br />
<br />
Proposal:<br />
Option 1: Add the following rule to the chapter 27: If no optional
attribute is specified or its value is different than the standardized
strings (i.e. "explicit omit", "implicit omit"), rules for "explicit
omit" apply.<br />
<br />
Option 2: Change some rules in 6.2.1.0, 6.2.1.1.a and 27:<br />
[6.2.1.0 - assignment list notation]<br />
When the assignment notation is used in a scope, where the optional
attribute is either unspecified or set to "explicit omit", optional and
mandatory fields, not directly referred to in the notation shall remain
unchanged. When optional fields of variables are not assigned
explicitly, they are uninitialized (i.e. the optional attribute shall
not have any effect on variables as described in clause 27.7 restriction
a)).<br />
<br />
[6.2.1.0 - value list notation]<br />
When using value list notation in a scope where the optional attribute
is either unspecified or set to "explicit omit", all remaining fields at
the end of the type definition, missing from the value list notation,
are left unchanged.<br />
<br />
[6.2.1.1.a]<br />
When expanding a value or value field of record type, the subfield
referenced in the dot notation shall be set to present and all
unreferenced mandatory subfields shall be left uninitialized; when the
assignment is used in a scope where the optional attribute is either
unspecified or equal to "explicit omit", all unreferenced optional
subfields shall be left undefined. When the assignment is used in a
scope where the optional attribute is equal to "implicit omit", all
unreferenced optional subfields shall be set to omit.<br />
<br />
[27]<br />
Add the following rule: If the optional attribute has a different value
than the standardized string (i.e. "explicit omit", "implicit omit"), it
is considered as if the optional attribute was unspecified.</td>
