Description:
 def subtype(self, **kwargs):
 """Create a specialization of |ASN.1| schema object. The `subtype()` method accepts the same set arguments as |ASN.1| class takes on instantiation 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| type/value 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.
