Keyword Args
    ------------
    value: :class:`str`, :class:`bytes` or |ASN.1| object
        :class:`str`, alternatively :class:`bytes`
        representing octet-stream of serialised unicode string
        (note `encoding` parameter) or |ASN.1| class instance.
        If `value` is not given, schema object will be created.

tagSet: :py:class:`~pyasn1.type.tag.TagSet`
        Object representing non-default ASN.1 tag(s)

subtypeSpec: :py:class:`~pyasn1.type.constraint.ConstraintsIntersection`
        Object representing non-default ASN.1 subtype constraint(s). Constraints
        verification for |ASN.1| type occurs automatically on object
        instantiation.

encoding: :py:class:`str`
        Unicode codec ID to encode/decode
        :class:`str` the payload when |ASN.1| object is used
        in octet-stream context.

Raises
    ------
    ~pyasn1.error.ValueConstraintError, ~pyasn1.error.PyAsn1Error
        On constraint violation or bad initializer.
