<br />
That means that two structured types which contain an enumerated type and have the same form in every aspect also are not compatible to each other, even though that is true for all base types and all other structured types.<br />
<br />
Example:<br />
<br />
type record A {<br />
&#160;&#160;integer i (1..200) optional<br />
}<br />
<br />
is compatible to<br />
<br />
type record B {<br />
&#160;&#160;integer j (1..200) optional<br />
}<br />
<br />
but <br />
<br />
type record A2 {<br />
&#160;&#160;enumerated { a, b } e optional<br />
}<br />
<br />
is not compatible to<br />
<br />
type record B2 {<br />
&#160;&#160;enumerated { a, b } f optional<br />
}<br />
<br />
This, in my view, is an unnecessary language inconsistency which, for instance, prevents simple value-translation from an old, compatible type to a new one.<br />
<br />
It is also unclear why this restriction is imposed at all.<br />
<br />
Therefore, I propose to add a type-compatibility rule that states that any enumerated value b of enumerated type B is compatible with enumerated type A if an enumerated value with the same name also exists in A and has the same number associated with it as b in B. Naturally, then, an enumerated type B is compatible to an enumerated type A if all its values are compatible with A.<br />
<br />
If this rule is introduced, an enumerated type essentially behaves like a restricted integer type, though still not compatible with integer types but only with other enumerated types.</td></tr><tr class="print"><td class="print-category">Steps To Reproduce</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Additional Information</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Tags</td><td class="print" colspan="5">No tags attached.</td></tr><tr class="print"><td class="print-category">Relationships</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Attached Files</td><td class="print" colspan="5"><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR7450.docx (151,319) <span class="italic">19-07-2016 15:51</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3418&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR7450-2.docx (170,763) <span class="italic">19-07-2016 16:33</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3419&amp;type=bug</td></tr><tr><td class="print-spacer" colspan="6"><hr size="1" /></td></tr><tr><td class="form-title">Issue History</td></tr><tr class="print-category"><td class="row-category-history">Date Modified</td><td class="row-category-history">Username</td><td class="row-category-history">Field</td><td class="row-category-history">Change</td></tr><tr class="print"><td class="print">15-07-2016 12:50</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=508">Jacob Wieland - Spirent</a></td><td class="print">New Issue</td><td class="print"></td></tr><tr class="print"><td class="print">18-07-2016 09:56</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=82">Jens Grabowski</a></td><td class="print">Assigned To</td><td class="print"> =&gt;
