------------------------------------------------------

Vote to solve this issue.

I'm having same issue but this time with empty anchor elements and CSS. I'll quote Sourceforge's
https://sourceforge.net/tracker/?func=detail&atid=373747&aid=1803803&group_id=21935

"
Resulting xhtml output arises Mozilla's #265324 in Core component (same
problem in IE).

Generated empty anchor (<a id="some-id" />) element give CSS problems when
applying CSS styling, example css snippet:

a
{
color: blue;
text-decoration: underline;
}

a:hover
{
background: rgb(75%,75%,100%);
color: blue;
text-decoration: underline;
}
"

> C.3. Element Minimization and Empty Element Content

It's not a rule, rather guidelines, but I think compatibility it's Xalan-J's concern. Maybe
there could be a ''compatibility'' flag for XHTML output where noticed in XSL stylesheets
(an extension)?.

> - The output:
> > <?xml version="1.0" encoding="iso-8859-1"?>
> > <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
> "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

> > </head>
> > <body>
> > <div />
> > </body>
> > </html>
> - The standards:
> > Empty-element tags MAY be used for any element which has no content, 
> > whether or not it is declared using the keyword EMPTY.
> > For interoperability, the empty-element tag SHOULD be used, and
> > SHOULD only be used, for elements which are declared EMPTY.
> (http://www.w3.org/TR/REC-xml/#sec-starttags)
> > C.3. Element Minimization and Empty Element Content
> > Given an empty instance of an element whose content model 
> > is not EMPTY (for example, an empty title or paragraph) do
> > not use the minimized form (e.g. use <p> </p> and not <p />).
> (http://www.w3.org/TR/xhtml1/#guidelines)
> - The patch:
> Elements like <p> or <div> aren't declared as EMPTY in the XHTML DTD.
> According to XML and XHTML standards, the <div></div> form should be used
> instead of <div/>. Both are XML (and XHTML) valid, but the second leads to
> strange problems with some browsers (guess who --- IE).
> Hope this helps,
> Marco
