'Create a copy of a |ASN.1| type or object.
Any parameters to the *clone()* method will replace corresponding
properties of the |ASN.1| object.
Parameters
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)
sizeSpec: :py:class:`~pyasn1.type.constraint.ConstraintsIntersection`
Object representing non-default ASN.1 size constraint(s)
Returns
new instance of |ASN.1| type/value'
