Set HTML5 doctype with XSLT

How would I cleanly set the doctype of a file to HTML5 <!DOCTYPE html> via XSLT (in this case with collective.xdv)

The following, which is the best my Google foo has been able to find:

<xsl:output
    method="html"
    doctype-public="XSLT-compat"
    omit-xml-declaration="yes"
    encoding="UTF-8"
    indent="yes" />

produces:

<!DOCTYPE html PUBLIC "XSLT-compat" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

You must use XHTML 1.0 Strict as the doctype if you want XHTML output consistent with HTML5, libxml2's xml serializer has a special output mode triggered by the XHTML 1.0 doctypes that ensures output is XHTML compatible, (e.g. <br /> rather than <br/>, <div></div> rather than <div/>). doctype-system="about:legacy-compat" does not trigger this compatibility mode

If you are happy with html output, then setting <xsl:output method="html"> should do the right thing. You can then set the doctype with <xsl:text disable-output-escaping="yes">&lt;!DOCTYPE html&gt;</xsl:text>, though this will need plumbing in at the appropriate place as XDV does not support this yet.

In fact it seems <xsl:output method="html"/> does not really help either - this will result in <br/> being output as <br></br>.

I think this is currently only supported by writing the doctype out as text:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="html" encoding="utf-8" indent="yes" />

  <xsl:template match="/">
    <xsl:text disable-output-escaping='yes'>&lt;!DOCTYPE html&gt;</xsl:text>
    <html>
    </html>
  </xsl:template>

</xsl:stylesheet>

This will produce the following output:

<!DOCTYPE html>
<html>
</html>

<xsl:output
     method="html"
     doctype-system="about:legacy-compat"
     encoding="UTF-8"
     indent="yes" />

this outputs 

<!DOCTYPE html SYSTEM "about:legacy-compat">

this is modified as my fix to http://ukchill.com/technology/generating-html5-using-xslt/

With Saxon 9.4 you can use:

<xsl:output method="html" version="5.0" encoding="UTF-8" indent="yes" />

This generates:

<!DOCTYPE HTML>

This variation of Jirka Kosek's advice, via Advanced XDV theming on Plone.org seems to work for me in collective.xdv.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output
      doctype-public="HTML"
      doctype-system=""/>
</xsl:stylesheet>

The following code will work as a standalone template if saved as html5.xml:

<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="html5.xml"?>
<xsl:stylesheet version="1.0"
            xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/xhtml"
            >
<xsl:output method="xml" encoding="utf-8" version="" indent="yes" standalone="no" media-type="text/html" omit-xml-declaration="no" doctype-system="about:legacy-compat" />

<xsl:template match="xsl:stylesheet">
  <xsl:apply-templates/>
</xsl:template>

<xsl:template match="/">
  <html>
    <head>
      <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
    </head>
    <body>
      <xsl:text>hi</xsl:text>
    </body>
  </html>
</xsl:template>

</xsl:stylesheet>
