* fix(xslt): name the html output method doctype HTML, not the element name XSLT 1.0 16.2: for the html output method the name following <!DOCTYPE should be HTML or html, not the document element name (which is the xml method's rule, 16.1). The serializer used the document element name for both methods, so method=html with a non-html root element (e.g. <root>) emitted <!DOCTYPE root PUBLIC ...> instead of <!DOCTYPE HTML PUBLIC ...>. Closes Apache Xalan conformance cases output40, output48, output60. * fix(xslt): emit no html doctype when the result has no element Addresses the doctype critic finding: a doctype precedes the first element (16.2), so a text-only result must emit none even for the html method. The fixed HTML name made the existing no-element guard unreachable; restore it by guarding on the document element before choosing the name.
