'Indicate if |ASN.1| component is set and represents ASN.1 type or ASN.1 value.
The PyASN1 type objects can only participate in types comparison
and serve as a blueprint for serialization codecs to resolve
ambiguous types.
The PyASN1 value objects can additionally participate in most
of built-in Python operations.
Returns
: :class:`bool`
:class:`True` if |ASN.1| component is set and represent value and type,
:class:`False` if |ASN.1| component is not set or it represents just ASN.1 type.'
