Description

My XSLT contains a doctype declaration like so:

<xsl:output method="html" version="1.0" encoding="UTF-8"
omit-xml-declaration="yes" indent="yes" doctype-system="about:legacy-compat"
media-type="text/html" />

When executing a transform and serializing this to a SAXResult with a LexicalHandler attached, the startDTD method on the lexical handler is not called.

Some debugging in the Xalan classes shows that org.apache.xml.serializer.SerializerBase.setDoctypeSystem(String) is invoked during the transformation process, but the implementation does not persist the parameter in the m_doctypeSystem field. This field is however used by org.apache.xml.serializer.SerializerBase.getDoctypeSystem() to read the doctype back.

In comparison, the streaming implementation of the serializer sets this value:
if (OutputKeys.DOCTYPE_SYSTEM.equals(name)) {
this.m_doctypeSystem = val;

The
org.apache.xml.serializer.ToXMLSAXHandler.startElement(String, String, String, Attributes)

relies on this value to be set to pass it on to the lexical handler.
String doctypeSystem = getDoctypeSystem();
if (doctypeSystem != null && m_lexHandler != null)

So it looks like org.apache.xml.serializer.ToXMLSAXHandler or one of its super classes should handle the "doctype-system" property explicitly.
