(e) allow <text/> only


<attribute name="id" a:attributeType="id">
  <text/>
</attribute>

I think this is less confusing.


If we allow something like

<attribute name="id" a:attributeType="id">
  <data type="decimal" datatypeLibrary="W3C XML Schema"/>
</attribute>

Then I guess users may think that <foo id="0"/> and <foo id="0.0"/> will
collide.
