Workaround: generate explicit closing tag in XSLT

It looks like the PHP XSLT functions have a bug when generating HTML output: they generate self-closing <script src="..."/> tags that cause Internet Explorer to hickup, although the XSLT transformation engines should take care of HTML peculiarities (including the set of <script></script> tags) when you set xsl:output to html.

The workaround provided in PHP documentation comes handy in any situation where you want to have an explicit closing tag for whatever reason. Instead of <tag></tag> which is usually output as <tag />, your XSLT transformation should contain <tag><xsl:comment /></tag>, which will generate the opening and closing tag.
