"""A Model With Default Views of Various Types
A model with default views has several predefined views,
each associated with a given type. This is often used for
when a submodel should have an attached view, but the view
differs depending on the serialization format
Parameters are as the superclass, except for any
parameters ending in '_view': these parameters
get stored as default views.
The default 'default views' are
text
:class:`oslo_reports.views.text.generic.KeyValueView`
xml
:class:`oslo_reports.views.xml.generic.KeyValueView`
json
:class:`oslo_reports.views.json.generic.KeyValueView`
