DNSSEC EPP Extension (RFC 4310) Usability Question

In reviewing the DNSSEC EPP Extension (RFC 4310) I noticed one usability
issue that I would like to get feedback from the existing implementations of
the extension.  

The specification allows adding (<secDNS:add>), removing (<secDNS:rem>), and
changing (<secDNS:chg>) DS data, but according to the XML schema they can¹t
be done at the same time.  Below is from the RFC 4210 XML schema for the
<secDNS:update>:

     <complexType name="updateType">
       <choice>
         <element name="add" type="secDNS:dsType"/>
         <element name="chg" type="secDNS:dsType"/>
         <element name="rem" type="secDNS:remType"/>
       </choice>
       <attribute name="urgent" type="boolean" default="false"/>
     </complexType>
 
To allow for a mix of add, chg, and rem, should the XML schema model in the
Domain Mapping (RFC 4931) updateType XML schema definition be used?  I
updated the DNSSEC XML schema below to match the definition of the Domain
Mapping, to support the mix of add, chg, and rem:

      <complexType name="updateType">
       <sequence>
         <element name="add" type="secDNS:dsType" minOccurs=²0² />
         <element name="chg" type="secDNS:dsType" minOccurs=²0² />
         <element name="rem" type="secDNS:remType" minOccurs=²0² />
       </sequence>
       <attribute name="urgent" type="boolean" default="false"/>
     </complexType>
 
Has any of the current implementations come across this issue?
