[Doxygen-projects] aliases issue ?

[spamy <spa...@fr...>]

hi,
i'd like to customize an <hr> tag

I defined an alias with : ALIASES +=myruler="<hr class='myruler'>"  

but "class" is not used in html code.

In HTML code of the page, i just obtain :
<hr/> 
class is erased.
with style, instead of class it's the same.

if I define the alias with : ALIASES +=myruler="<hr class='myruler'/>"
gives :Warning: HTML tags may not use the 'empty tag' XHTML syntax.
 
Somebody could tell what's wrong ?

thanks
