tion except that all parameters
        of the `subtype()` method are optional.

        With the exception of the arguments described below, the rest of
        supplied arguments they are used to create a copy of `self` taking
        precedence over the ones used to instantiate `self`.

        The following arguments to `subtype()` create a ASN.1 subtype out of
        |ASN.1| type:

        Other Parameters
        ----------------
        implicitTag: :py:class:`~pyasn1.type.tag.Tag`
            Implicitly apply given ASN.1 tag object to `self`'s
            :py:class:`~pyasn1.type.tag.TagSet`, then use the result as
            new object's ASN.1 tag(s).

        explicitTag: :py:class:`~pyasn1.type.tag.Tag`
            Explicitly apply given ASN.1 tag object to `self`'s
            :py:class:`~pyasn1.type.tag.TagSet`, then use the result as
            new object's ASN.1 tag(s).

        subtypeSpec: :py:class:`~pyasn1.type.constraint.ConstraintsIntersection`
            Add ASN.1 constraints object to one of the `self`'s, then
            use the result as new object's ASN.1 constraints.

        Returns
        -------
        :
            new instance of |ASN.1| schema or value object

        Note
        ----
        Due to the immutable nature of the |ASN.1| object, if no arguments
        are supplied, no new |ASN.1| object will be created and `self` will
        be returned instead.
