Clinical modellers,

I'm trying to work out the latest design of Lab archetypes. A Lab result 
seems to now be a structure like the following:

  * openEHR-EHR-*OBSERVATION*.*laboratory_test_result*
      o + at0097|Test findings|:
        openEHR-EHR-*CLUSTER*.*laboratory_test_panel* [*]
          + +at0002 |Laboratory Result|: *CLUSTER* [*]
              # +at0004 |Reference range guidance|
              # +at0005 |Result status|
              # +at0014 |Result Detail|: [open slot] - ?  
                openEHR-EHR-*CLUSTER*.*laboratory_test_analyte* [*]
                  * +at0001 |Analyte Result|: *DATA_VALUE*
                  * +at0003 |Comment|: *DV_TEXT*
                  * etc


  * is this a correct understanding of the current design?
  * where would the LOINC code for each analyte go?
  * we could build some common test panels by specialising the test
    analyte archetype into things like TSH, TS4, etc and lab test panel
    into 'thyroid test'  - is anyone doing this?
  * how does AQL querying work if LOINC is not in use / not available?

It would be good if there was a design page on this e.g. in the openEHR
