The BOM export section is a kind of enhanced <part> information.
Under <part> the <bomcategory> is only referenced.
<part>
<bom category="...">
<splittable>...</splittable>
</bom>
...The complete definition can be found under <bomexport>.
Many parts use the same information, so it works like an attribute set.
<bomexport>
<bom category="..." vname="..." >
<exportvars>...</exportvars>
<bomid>...</bomid>
<exportvars>...</exportvars>
<lengthvar>...</lengthvar>
<heightvar>...</heightvar>
<widthvar>...</widthvar>
</bom>
</bomexport> <bomexport>
<bom category="transport" vname="Transport" >
<exportvars>L</exportvars>
<bomid>ARTNR</bomid>
<exportvars>V</exportvars>
<lengthvar>L</lengthvar>
<heightvar>HE</heightvar>
<widthvar>BR</widthvar>
</bom>
</bomexport>
