    """
    Loaded after installing this module, and before the next module starts
    installing.

    Add XSD Validation Schema for a demo report if it's in the system.
    Demo data records are always created with `noupdate == True` and render of
    tag `report` doesn't support new `ir.actions.report` field `xsd_schema`.
    Thus it is impossible to define `xsd_schema` in the demo definition or add
    schema after that via xml update record. Therefore it possible to add value
    to `xsd_schema` field for demo record only via hook.

    Args:
     * cr(odoo.sql_db.Cursor) - database cursor.
     * registry(odoo.modules.registry.RegistryManager) - a mapping between
     model names and model classes.
