<td class="print-category">Description</td>
<td colspan="5" class="print">Nowadays, it is possible that an old
module for a previous version of TTCN-3 is imported into a module with a
newer language tag or that uses packages that the imported module does
not use.<br />
<br />
This can lead to the situation that in the newer/more-package-heavy
module some identifiers that are totally valid identifiers in the other
module are keywords and thus, not valid identifiers anymore.<br />
<br />
The importing module would then not be able to reference the imported
items.<br />
<br />
To solve this problem, an identifier escape mechanism should be
introduced so that the importing module can use the escape-notation when
using an identifier from the imported module that is a keyword in the
importing one.<br />
<br />
A simple solution would be to allow the identifier to be put into single
tick characters (same as octetstring etc):<br />
<br />
'value'<br />
.<br />
This syntax can be used everywhere that an identifier can be used,
e.g.<br />
<br />
t.'value'<br />
<br />
On the lexer-level there is unfortunately a prefix-overlap with
octetstring and hexstring literals that start with digits above 9 (i.e.
A B C D E F), but since the new syntax would not end in 'O or 'H, this
lexical issue can be resolved.</td>

It sound like we need some mapping rules between the language versions

their old modules.<br />
Mixing different language versions in the same project can be dangerous
if users do not check the language identifier in each module before they
change it.<br />
Also if users are not perfectly sure in the minute differences in each
language version they are using.<br />
<br />
Would it be a good idea to include support for very old language version
into the list of features that can be deprecated?<br />
What do you think, if the standard would only support old version only
up to a specified time or version number difference - like usually done
with software - would that be a good incentive for users to
upgrade?</td>
