Missed this the first time round. Dan Connolly's XMLisation of Turtle:

For example

<#pat> <#child>  <#al>, <#chaz>, <#mo> ;
        <#age>    24 ;
        <#eyecolor> "blue" .

becomes...

<thing ref="#pat">
   <rel ref="#child">
     <thing ref="#al"/>
     <thing ref="#chaz"/>
     <thing ref="#mo"/>
   </rel>
   <rel ref="#age"><val int="24"/></rel>
   <rel ref="#eyecolor"><str>blue</str></rel>
  </thing>
