I have created a little module to tweak the display of sales order lines shown in the quote/order form view.  The original view has both "Product" and "Description" at the beginning of each line.  The "Description" column is actually displaying the "name" field.  Since these two fields end up displaying the same data, I want to hide or remove the name field.  In my view code, I have tried:

<field name="name" position="replace"/>

and

<field name="name" position="replace">
    <field name="name" invisible="1"/>
</field>

Neither works, even though I have set the view priority all the way down to 1.  I have also tried simply changing the label on the name field, like this:

<field name="name" position="attributes">
    <attribute name="string" >Part Num.</attribute>
</field>

This also has no effect on the display.  If my view has the lowest priority (sequence) number, then why do my changes have no effect?
