To declare an HTML5 doctype, `<! DOCTYPE html>` is required in the first line of your HTML document. Doctype declaration for HTML5 is not case sensitive and does not require a closing tag.
If you need to use the javascript in the transformation (for example, it contains a set of extension functions that are called within the transformation), you need to put the javascript contents (at least that of one javascript file) in a separate XSLT stylesheet file, using the proper extension element (such as <msxml ...
Returns the contents of the current group selected by xsl:for-each-group. Available in XSLT 2.0 and later versions. Available in all Saxon editions. current-group() ➔ item()*
XSLT <xsl:text> The <xsl:text> element is used to write literal text to the output. Tip: This element may contain literal text, entity references, and #PCDATA.
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'><!DOCTYPE html></xsl:text>
<html>
</html>
</xsl:template>
</xsl:stylesheet>
This will produce the following output:
<!DOCTYPE html>
<html>
</html>
To use the simple HTML doctype <!DOCTYPE html>, you have to use the disable-output-escaping feature: <xsl:text disable-output-escaping="yes"><!DOCTYPE html></xsl:text>. However, disable-output-escaping is an optional feature in XSLT, so your XSLT engine or serialization pipeline might not support it.
For this reason, HTML5 provides an alternative doctype for compatibility with HTML5-unaware XSLT versions (i.e. all the currently existing versions of XSLT) and other systems that have the same problem. The alternative doctype is <!DOCTYPE html SYSTEM "about:legacy-compat">. To output this doctype, use the attribute doctype-system="about:legacy-compat" on the xsl:output element without using a doctype-public attribute at all.
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" doctype-system="about:legacy-compat"/>
...
<html>
</html>
</xsl:stylesheet>
<xsl:output
method="html"
doctype-system="about:legacy-compat"
encoding="UTF-8"
indent="yes" />
this outputs
<!DOCTYPE html SYSTEM "about:legacy-compat">

With Saxon 9.4 you can use:
<xsl:output method="html" version="5.0" encoding="UTF-8" indent="yes" />
This generates:
<!DOCTYPE HTML>
