More specifically, <head/> is disallowed because the [X]HTML spec
requires <head> sections to include <title>, so the briefest you can
get is <head><title/></head>

The space is optional but recommended as a best-practice, especially
for non-XML HTML4 compatibility (the top of Guenther's link #2 reads:
"This appendix summarizes design guidelines for authors who wish their
XHTML documents to render on existing HTML user agents").
