Use the <bomformat> element to define how to display the data collected in earlier <bom> elements. It takes a category attribute that specifies the logical name of a BOM category, and a title attribute to specify the display name for the category. A structure of <section> elements that contain <field> elements defines the layout, as in the following example:
<bomformat category="Detail" title="Change Details">
<section name="descriptions" parent="section name" expandable="yes">
<field name="Description" title="Change Description"/>
</section>
<section name="diff">
<field name="Diff" title="Differences"/>
</section>
