(Note: this is not limited to the Genetic Encoding project.)

I note with some minor degree of guilt that the hand= attribute of
att.transcriptional is declared as data.pointer, but the new=
attribute of <handShift>, which seems to perform exactly the same
function, is declared as data.code. Since both of these datatypes
boil down to xsd:anyURI, there is no formal constraint difference,
but nonetheless, seems to me they should match.

Furthermore, each is constrained (by the prose in their respective
<valDesc>s) to point to a single <handNote>. Two thoughts:

1) The prose for hand= of att.transcriptional is clearer and more
   precise than that of new= of <handShift>, and

2) This is an unfortunate restriction: these attributes should be
   able to point to an <alt> or <link> to express, e.g., that either
   A or B wrote the passage, not sure which. Either that or the
   Guidelines should explicitly demonstrate some other mechanism for
   expressing this idea formally. E.g.

      <handNotes>
        <handNote xml:id="scribeA"      scribe="A"/>
        <handNote xml:id="scribeB"      scribe="B"/>
        <handNote xml:id="scribeIdunno" scribe="AorB"/>
      </handNotes>

   or

      <handNotes>
        <handNote xml:id="scribeA" scribe="A"/>
        <handNote xml:id="scribeB" scribe="B"/>
        <handNote xml:id="scribeProbablyA">
          <alt targets="#scribeA #scribeB" mode="excl" weights="0.7 0.3"/>
        </handNote>
      </handNotes>

   or some such.

     <quote>The ultimate weakness of violence is that it is a
     descending spiral, begetting the very thing it seeks to
     destroy. Instead of diminishing evil, it multiplies it. Through
     violence you may murder the liar, but you cannot murder the
     lie, nor establish the truth. Through violence you murder the
     hater, but you do not murder hate. In fact, violence merely
     increases hate &#x2026; Returning violence for violence
     multiplies violence, adding deeper darkness to a night already
     devoid of stars. Darkness cannot drive out darkness; only light
     can do that. Hate cannot drive out hate: Only love can do
     that.</quote>
