display email of author in articleinfo

Hiho,

finally I ventured out to do my first customizations and thanks to 
Norm's HTML Parameter Reference I got pretty nice results :)

As I went on to individual tag customizations I got stuck. Flying over 
Bob's XSL bible, I thought I could manage to achieve the customizations 
that I had in mind, but given my limited XSL knowledge (or shall I say 
non-existent ;o) I couldn't transfer its example to my problem and the 
latest XSL stylesheets.

I have an authorgroup with 2 authors in my articleinfo. Their firstnames 
and surnames get displayed fine, but their email tags get suppressed. 
How can I get their email addresses to be displayed on the titlepage?


Thanks for your kind help,
Patrick
