SV: [ubl] use of 'ID' in documents

I am not sure how you would handle this in the spreadsheets but W3C
schema is capable of modeling this situation:

<xsd:sequence>
 <xsd:choice minOccurs="1">
	<xsd:element ref="BuyersID"/>
	<xsd:element ref="SellersID"/>
 </xsd:choice>
<xsd:element ref="CopyIndicatory"/>
. . .
</xsd:sequence>

If the choice is optional, i.e., no BuyersID or SellersID, then the
"minOccurs" attribute would be set to 0.
