				In ASN.1 there are basically three set operations to construct subtype constraints: UNION, INTERSECTION, EXCLUSION<br />
<br />
UNION can be mapped to the &quot;value&quot;-list construct:<br />
<br />
A UNION B -&gt; (A, B)<br />
<br />
INTERSECTION could be mapped to the following <br />
(because A AND B == NOT (NOT A OR NOT B)):<br />
<br />
A INTERSECTION B =&gt; complement(complement(A), complement(B))<br />
<br />
EXCLUSION could be mapped to the following<br />
(because A EXCEPT B == A AND NOT B):<br />
<br />
A EXCEPT B =&gt; complement(complement(A), B)<br />
<br />
So, any set expression should be mappable by using combinations of value-list and complement matching mechanism symbols.<br />
<br />
This, of course, would preclude that value-list is in actuality template-list, i.e. that even in type definitions, template constructions beside values and ranges are permitted (see CR5938).			</td>

				Considering the issue raised by the CR, my conclusion is that the way of handling set arithmetics doesn't need to be specified. Until the final result is the same, it shall be left as a tool implementation option. Therefore I just propose to add the paragraph below at the end of clause 9.1 (just after table 4):<br />
<br />
&quot;ASN.1 allows using set arithmethics in subtype constraints. In many cases these set arithmetics expressions shall be calculated before the translation to be able to convert the ASN.1 subtype into its associated TTCN-3 type. However, in some cases expressions can be translated to TTCN-3 in different ways; e.g. a UNION of consequtive integer values can be translated into a list of values, into a value range or a mixture of the two, while all these forms denote the same set of values. This standard leaves this choice open for tool implementations. The only requirement is that the resulted associated TTCN-3 type shall conform to this clause and clause 6 of ES 201 873 1 [1].&quot;<br />
<br />
Pls. review.<br />
