Certainly and since Ken already did most of the job for you a schematron
schema could look like:

<schema xmlns="http://www.ascc.net/xml/schematron">
 <pattern>
  <rule context="*">
   <report test="following-sibling::*[name(.)=name(current())]"
   >There can only be one <name/> element at the same level.</report>
  </rule>
 </pattern>
</schema>
