default field value from xml in odoo

ODOO

to explain it , Let us say we have selection field type which is has two selection values "in , out " as bellow 

type = fields.Selection([('in','In'),('out','Out'), string="Type"])

 and we want to make it's default value "in" from xml , so when we create our view we can pass the default value "in" with context as bellow 

<record id="view_id_form" model="ir.ui.view">
            <field name="name">model.model.form</field>
            <field name="model">model.model</field>

            <field name="context">{'default_type':'in'}</field>

            <field name="arch" type="xml"> 

            <form>
