[tei-council] num

[Sebastian Rahtz]

I am inclined to agree with Lou's argument
that we should not re-invent datatypes with
paired attributes.  but
why not simply extend our data.numeric to also
support rational numbers? then Gabriel
can just use @value="22/7" as he needs.

there is prececedent - several of our data.*
types are the W3C ones plus additions. data.numeric
itself is already

<rng:choice>
      <rng:data type="double"/>
      <rng:data type="decimal"/>
    </rng:choice>

so why not change it to

<rng:choice>
      <rng:data type="double"/>
      <rng:data type="decimal"/>
      <rng:data type="token">
         <rng:param name="pattern">([\d\-]/[\d\-])</rng:param>
      </rng:data>
    </rng:choice>

(or does \d already allow for - prefix, ie "-1"?)
