author initials in bibliography entries

Dear all

I would like to know the appropriate markup for author initials in 
bibliography entries with multiple authors.

In DocBook 5.0, the element authorinitials can appear as children of 
biblioentry, bibliomixed, bibliomset, biblioset but not as children of 
author or personname. The following example is not valid:

<biblioentry xml:id="CR1">
   <authorgroup>
     <author>
       <personname>
         <authorinitials>P.</authorinitials>
         <surname>Abad</surname>
       </personname>
     </author>
     <author>
       <personname>
         <authorinitials>J.</authorinitials>
         <surname>Abad</surname>
       </personname>
     </author>
   </authorgroup>
   <title>The hundred greatest theorem of mathematics</title>
   <copyright>
     <year>1999</year>
   </copyright>
</biblioentry>

In my view, it would be good to allow authorinitials as child of 
personname. For now, I guess the use of a second firstname element with 
a certain role attribute would be a workaround. Please let me know if I 
missed anything.

Kind regards,

Martin
