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

Raises
------
~pyasn1.error.ValueConstraintError, ~pyasn1.error.PyAsn1Error
    On constraint violation or bad initializer
IndexError
    When idx > len(self)
