- The stylesheet:

> <?xml version="1.0" encoding="UTF-8"?>
>
> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
>
>   <xsl:output method="xml" version="1.0" encoding="iso-8859-1" indent="yes"
>             omit-xml-declaration="no" doctype-public="-//W3C//DTD XHTML 1.0
Strict//EN"
>         doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd" />

>   <xsl:template match="/">
>     <html>
>       <head>
>     <title>bug test</title>
>       </head>
>       <body>
>     <div></div>
>       </body>
>     </html>
>   </xsl:template>
>
> </xsl:stylesheet>


- 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">
> <html>
> <head>
> <title>bug test</title>
> </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
