        <h:p>This is purely conventional and used for bond/electron counting. There is no default value. The emptyString attribute can be used to indicate a bond of unknown or unspecified type. The interpretation of this is outside the scope of CML-based algorithms. It may be accompanied by a
          <h:tt>convention</h:tt>attribute on the
          <h:tt>bond</h:tt>which links to a dictionary. Example:
          <h:tt><bond convention="ccdc:9" atomRefs2="a1 a2"/></h:tt>could represent a delocalised bond in the CCDC convention.</h:p>
