How should the following value be handled in TTCN-3?<br />
&lt;DigestValue/&gt;<br />
<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 />

<td class="print">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: "Extensible Markup Language (XML) 1.1".
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>
