Thanks Dick.
Suggest an example would help others understand.
Simple para explaining how the combine attribute works
perhaps?
<add>
For example

   <define name="db.ubiq.inlines" combine="choice">
    <choice>
      <ref name="myelement1"/>
      <ref name='myelement2'/>
    </choice>
  </define>


<define name="myelement1">
   <text/>
</define>

This replaces or merges with the definition within the main
schema, due to the 'combine' attribute being set to 'choice'.
These two elements are added to the main definition.

Then when the schema is updated, the elements remain defined
without further work.
