/**
 * Class ExplicitlyTaggedObject decorate an inner object with an additional tag that gives information about
 * its context specific meaning.
 * Explanation taken from A Layman's Guide to a Subset of ASN.1, BER, and DER:
 * >>> An RSA Laboratories Technical Note
 * >>> Burton S. Kaliski Jr.
 * >>> Revised November 1, 1993
 * [...]
 * Explicitly tagged types are derived from other types by adding an outer tag to the underlying type.
 * In effect, explicitly tagged types are structured types consisting of one component, the underlying type.
 * Explicit tagging is denoted by the ASN.1 keywords [class number] EXPLICIT (see Section 5.2).
