<p>This function returns the value <b><font face="Courier New">true</font></b> if and only if the template parameter is completely initialized, thus, contains only concrete or omitted values,
with the following exception: isbound returns true for a record-of value which contains both bound and unbound elements, whereas <a href="isvalue.html">isvalue</a> returns false.
