I was thinking of a way to indicate the maximum retry attempts in this exception.

However, it's best to leave that to the framework using web-poet to standardize limits, delays, etc.

"""Indicates that there's something wrong with :class:`~.ResponseData` and
it needs to be downloaded again.

You should use this in instance where the HTTP Response is malformed, missing
some required information, etc.

This should be raised inside the subclasses of :class:`~.WebPage` or anything
which requires :class:`~.ResponseData` as a dependency. The framework which
handles the Page Objects should then attempt to create a new instance with a
fresh :class:`~.ResponseData` dependency.
