But in part 1 it is mostly defined what compatibility of a value with a type means. Compatibility of types is defined in only some cases.<br />
<br />
I suggest to clarify the type compatibility such that operands of relational operators have to be of the same root type. As a consequence values of different subtypes of integer can be compared, even if the subtypes have an empty intersection.<br />
<br />
Similarly for the list operator &amp;, type compatibility of the operands is too strong. It is sufficient that the operands are of the same root type.</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">From discussion with Raul Alfonso Quintana, MTP</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"><table border="0" width="100%" cellpadding="0" cellspacing="1"><tr><td class="print"><span class="nowrap">related to</span>&#160;</td><td class="print">0004850</td><td class="print">closed&#160;</td><td class="print"><span class="nowrap"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=81">Ina Schieferdecker</a></span>&#160;</td><td class="print">type compatibility of union does not coincide with union equality&#160;</td></tr></table></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="doc" />&#160;CR4508_Expressions.doc (65,536) <span class="italic">09-12-2008 11:16</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=1867&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="doc" />&#160;CR4508_Expressions_02.doc (67,072) <span class="italic">09-12-2008 12:41</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=1869&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="doc" />&#160;CR4508_Expressions_03.doc (82,432) <span class="italic">18-12-2008 15:44</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=1915&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="doc" />&#160;CR4508_Expressions_04.doc (79,360) <span class="italic">19-12-2008 09:01</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=1918&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="doc" />&#160;CR4508_Expressions_05.doc (87,040) <span class="italic">20-12-2008 15:49</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=1923&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">28-11-2008 14:14</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=112">Thomas DeiÃŸ</a></td><td class="print">New Issue</td><td class="print"></td></tr><tr class="print"><td class="print">28-11-2008 14:14</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=112">Thomas DeiÃŸ</a></td><td class="print">Status</td><td class="print">new =&gt;

There is one issue regarding equality of union values. As defined this does not fit to compatibility of union values. In that sense the text would be contradicting itself. To require that equality of union values also includes the choice of the alternative would be a backward incompatible change, hence I am not sure whether we should the specification in this way.<br />

Btw.: this CR is a quite late one, it should not hurt if that one is postponed to 2009.			</td>
