Please assess if ticket is still valid and add a description to the ticket

This was meant as a maintenance ticket.

Many of the IDFs could likely become a lot shorter by using the <locations> tag to replace equilly spaced <location> tags.

At this point I have done this for LET, which described here, http://www.mantidproject.org/IDF#Using_.3Clocations.3E , reduced IDF from 1590 to 567 lines.

It is not a high priority, and perhaps rather than doing a mass conversion of all IDFs as suggested with this ticket, just convert IDF on case by case basis and where users can benefit from a shorter IDF.

Hence, writing this I am indifferent as to whether or not to close this ticket.

While working on #9136, I've found another example of potential space for improvements. It's the MUSR definition:

  <type name="ring-front">
    <component type="pixel">
    <location r="0.14" t="90" p="309.375000" rot="309.375000" name="det33"/>    
    <location r="0.14" t="90" p="298.125000" rot="298.125000" name="det34"/>
    <location r="0.14" t="90" p="286.875000" rot="286.875000" name="det35"/>
    ... more lines ...
    <location r="0.14" t="90" p="28.125000" rot="28.125000" name="det58"/>
    <location r="0.14" t="90" p="16.875000" rot="16.875000" name="det59"/>
    <location r="0.14" t="90" p="5.625000" rot="5.625000" name="det60"/>
    <location r="0.14" t="90" p="354.375000" rot="354.375000" name="det61"/>
    <location r="0.14" t="90" p="343.125000" rot="343.125000" name="det62"/>
    <location r="0.14" t="90" p="331.875000" rot="331.875000" name="det63"/>
    <location r="0.14" t="90" p="320.625000" rot="320.625000" name="det64"/>
    </component>    
  </type>  

This might be replaced with much shorter (and consequently less error-prone):

  <type name="ring-front">
    <component type="pixel">
      <locations r="0.14" t="90" p="309.375000" p-end="5.625000" rot="309.375000" rot-end="5.625000" name="det" n-elements="28" name-count-start="33"/>
      <locations r="0.14" t="90" p="354.375000" p-end="320.625000" rot="354.375000" rot-end="320.625000" name="det" n-elements="4" name-count-start="61"/>
    </component>
  </type>  

I believe that EMU, ARGUS and HIFI have similar structures as well.
