This test and others in this group expect a minimized tag syntax of <x/> rather than <x /> (or indeed <x />). While the specification permits this when html-version is 5.0 or more, it does not mandate it. Quoting the specification: If an element that has no children is expected to be empty, the serializer MUST use the minimized tag syntax, for example <br />, as the alternative syntax <br></br> allowed by XML gives uncertain results in many legacy user agents. If the html-version serialization parameter is absent or has a value less than 5.0, the serializer MUST include a space before the trailing />, e.g. <br />, <hr /> and <img src="karen.jpg" alt="Karen" />.
I'm happy to fix this one, but can't guarantee to find all instances unless you list them. The tests here were pretty much auto-generated by converting Henry's HTML5 tests, and the results haven't been carefully inspected except to ensure that they match Saxon's results. Indeed, I see that I've auto-converted a number of place-holder tests that Henry never completed, and that do nothing useful - I'll get rid of those.
Thanks. I've enumerated the affected tests below. Serialization-xhtml-1a * Should permit <XXX\s*/> because html-version="4.0" and the elements are not in the XHTML namespace. Serialization-xhtml-20 * Should permit <html /> because html-version="4.0" and <html> is not in the XHTML namespace. Serialization-xhtml-23 * Should permit <foo /> because html-version="4.0" and <foo> is not in the XHTML namespace. Serialization-xhtml-24 * Should permit <foo/> or <foo /> because html-version="5.0" and <foo> is not an HTML element. Serialization-xhtml-35 * Should permit <html /> because html-version="4.0" so <html> is not HTML element "html". Serialization-xhtml-39 * Should permit <html><head /></html> because html-version="4.0" so <head> is not HTML element "head".
Tim, as far as I can see, for most of these, the element is not "expected to be empty" (because html-version=4 and the elements are in no namespace) and therefore minimised tag syntax must not be used. Have I misunderstood something?

Have I misunderstood > something? You're correct. I'd been caught out by the change from 1.0, where the rule only applied when the element was an XHTML element. * Given an empty instance of an XHTML element whose content model is not EMPTY (for example, an empty title or paragraph) the serializer MUST NOT use the minimized form. That is, it MUST output <p></p> and not <p />. ( If an element that has no children is an XHTML element with an EMPTY content model, the serializer MUST use the minimized tag syntax, for example <br />, as the alternative syntax <br></br> allowed by XML gives uncertain results in many existing user agents. The serializer MUST include a space before the trailing />, e.g. <br />, <hr /> and <img src="karen.jpg" alt="Karen" />. I'll recheck these before closing...

[Definition: The following XHTML elements have an EMPTY content model: area, base, br, col, embed, hr, img, input, link, meta, basefont, frame, isindex, and param.] [Definition: The void elements of HTML5 are area, base, br, col, embed, hr, img, input, keygen, link, meta, param, source, track and wbr.]
Test case fixed by removing the <command/> element from the test case.
Confirmed fixed. Thanks.
