+/**
+ * Class to represent ASN.1 construct "SEQUENCE OF".
+ * <p/>
+ * Extending classes should specify concrete types for T, generic collections can't be decoded (yet?).
+ * <p/>
+ * Usage example:
+ * <PRE>
+ * <code>
+ * {@literal @}Sequence
+ * public class Person {
+ *     {@literal @}IntRange(minValue=0, maxValue=100, hasExtensionMarker=true)
+ *     int age;
+ *     Children children;
+ * }
+ * public class Children extends {@code Asn1SequenceOf<ChildInformation> } {
+ *     public Children() { super(); }
+ *     public Children({@code Collection<ChildInformation>} coll) { super(coll); }
+ * }
+ * </code>
+ * </PRE>
+ *
+ * <p/>
+ * Actually, UPER decoder and encoder consider anything that extends {@code List<T>} as a SEQUENCE OF.
+ *
+ *
+ * @param <T> type of elements contained.
