<specGrpRef> processing

6 Jan 2019

      I don't get it. Can someone explain to me what the template for
<specGrpRef> in odds/odd2odd.xsl is doing around line 489 (dev
branch)?

It looks like the structure is:

  <choose>
    <when test="LOCAL POINTER">
      <apply-templates select="CHILDREN OF THAT WHICH IS POINTED TO"/> 
    </when>
    <otherwise>
      <for-each select="THAT WHICH IS POINTED TO"> <!-- to set context node -->
        <choose>
          <when test="child::specGrp">    ????
            <apply-templates select="child::specGrp/child::*"/>
          </when>
          <otherwise>
            <apply-templates select="child::*"/>
          </otherwise>
        </choose>
      </for-each>
    </otherwise>
  <choose>

I find this bizarre, but I may be missing something here. A
specGrpRef/@target is supposed to point to a <specGrp>. A <specGrp>,
of course, can contain children <specGrp>s (not that any of ours do
that). So it looks to me like ...

... given the following somewhere in file A.xml

  <specGrp xml:id="sciencyStuff">
    <elementRef key="measureGrp"/>
    <elementRef key="measure"/>
    <specGrp xml:id="detailedScienceStuff">
      <elementRef key="unit"/>
      <elementRef key="num"/>
    </specGrp>
  </specGrp>

... and the following in file B.xml

  <specGrpRef target="A.xml#sciencyStuff"/>

then odd2odd.xsl will only process 'unit' and 'num', not 'measureGrp'
and 'measure', for which I can see absolutely no reason.

Am I going nuts, here? Was there a period in ODD history when a
<specGrpRef> would point to the *parent* of the desired <specGrp>,
not to the <specGrp> itself?
