&lt;DigestValue/&gt;<br />

The element DigestValue is present so it is valid xml-value. But which template in TTCN-3 matches this value?<br />
template DigestValue tOmit:=omit; // should not match as the element is present<br />
template DigestValue tAnyValue:=?;  // perhaps should match as the element is present, but what is the value, if you try to save it to a variable?<br />

				The value of an empty element is an empty string. You can find the main guidelines in clause 3.1 of World Wide Web Consortium W3C® Recommendation: &quot;Extensible Markup Language (XML) 1.1&quot;. Additionally, the concept of empty elements and their string value can be derived from the definition of elements with no content described in this specification.<br />
<br />
As the XSD base64Binary type translates to an octetstring in TTCN-3, the correct result of decoding would be ''O meaning that tOmit wouldn't match and tAnyValue would produce a successful match, exactly as assumed.<br />
<br />
Hopefully this clarification is satisfactory. I don't think it is necessary to change anything in part 9 as the rules specifying values of XML elements are described in the XML specification.			</td>
