omponent of given ASN.1 type gets instantiated and appended to |ASN.1| sequence. Keyword Args ------------ value: :class:`object` or :py:class:`~pyasn1.type.base.PyAsn1Item` derivative A Python value to initialize |ASN.1| component with (if *componentType* is set) or ASN.1 value object to assign to |ASN.1| component. If `value` is not given, schema object will be set as a component. verifyConstraints : :class:`bool` If :obj:`False`, skip constraints validation matchTags: :class:`bool` If :obj:`False`, skip component tags matching matchConstraints: :class:`bool` If :obj:`False`, skip component constraints matching Returns ------- self z
