<td class="print-category">Description</td>
<td colspan="5" class="print">The current standard requires templates to
be at least partially initialized:<br />
<br />
15.0.d The expression or template body initializing a template shall
evaluate to a value or a template that is at least partially initialized
or to a matching mechanism.<br />
<br />
This is useful in cases when some templates are used as abstract,
containing just some basic values and the missing values are added in
templates derived from them.<br />
<br />
However, TTCN-3 language doesn't contain any mechanism that would allow
the user to distinguish between abstract templates containing partially
initialized values and fully initialized ones which could be safely used
in communication operations.<br />
<br />
Proposal:<br />
Add a specific modifier that would require a static template to be fully
initialized, e.g.<br />
<br />
template @concrete MyType mw_msg ....<br />
<br />
Since most templates are actually defined as fully initialized, more
logical would be to mark the abstract ones:<br />
<br />
template @abstract MyType mw_msgBase ....<br />
<br />
However, this approach would create a change that is not backwards
compatible.<br />
<br />
It should be also explained in detail whether restricted templates can
or may not be partially initialized.</td>

This might also be a tooling issue.<br />
For example we have a code quality check for partially initialized
items. So that users can pay special attention when working with them (+
creation and maintenance).<br />
This way does not have any runtime performance overhead, since it is
done on the code statically.</td>
