I think it depends on what you mean by doing it in odd.
If I got the point correctly, it would look like :

<elementSpec ident="seg" mode="change" module="linking">
                             <desc>seg is used to whatever you want to 
say here....</desc>
                             <content>
                                 <choice 
xmlns="http://relaxng.org/ns/structure/1.0">
                                     <group>
                                         <attribute name="type">
                                             <value>Type_01</value>
                                         </attribute>
                                         <attribute name="subtype">
                                             <choice>
                                                <value>a</value>
                                                 <value>b</value>
                                                  <value>c</value>
                                             </choice>
                                         </attribute>
                                     </group>
                                     <group>
                                         <attribute name="type">
                                             <value>Type_02</value>
                                         </attribute>
                                         <attribute name="subtype">
                                             <choice>
                                                 <value>x</value>
                                                 <value>y</value>
                                             </choice>
                                         </attribute>
                                     </group>
                                 </choice>
                                 <text 
xmlns="http://relaxng.org/ns/structure/1.0"/>
                             </content>
                         </elementSpec>

(sorry for the verbose relaxNG XML syntax).
