        <h:p>Of the form prefix:suffix where prefix and suffix are purely alphanumeric (with _ and -) and prefix is optional. This is similar to XML IDs (and we promote this as good practice for moleculeIDs. Other punctuation and whitespace is forbidden, so IDs from (say) PDB files are not satisfactory.</h:p>
        <h:p>The prefix is intended to form a pseudo-namespace so that molecule IDs in different molecules may have identical suffixes. It is also useful if the prefix is the ID for the molecule (though this clearly has its limitation). molecule IDs should not be typed as XML IDs since they may not validate.</h:p>
