+.SH "DESCRIPTION"
+Returns the value of one element inside a structure. 
+If an element is OPTIONAL and this returns
+\fBASN1_ELEMENT_NOT_FOUND\fP, it means that this element wasn't present

+then the keyword "?CURRENT" is also acceptable and indicates the
+current sequence element of this node.

+Note that there can be valid values with length zero. In these case
