It looks like the HTML for user-manual.html (unlike the reference manual and other articles) is not generated by asciidoc after all; instead, the rule in Documentation/Makefile uses xsltproc directly to convert the asciidoc-generated XML to HTML.

Apparently the caller is supposed to set the chunker.output.doctype-public parameter. http://www.sagehill.net/docbookxsl/Chunking.html#OutputDoctype

Maybe something as simple as this would work.

Subject: Documentation: set a !DOCTYPE for user manual

asciidoc already takes care of including a doctype for most of the HTML documentation, but the user manual which is processed with docbook-xsl directly lacks one (at least with Debian docbook-xsl 1.75.2+dfsg-5). This makes it harder to automatically validate the HTML.
