As a person who writes HTML/XHTML every single day, there are several
flaws in your argument:
- <head/> is not valid HTML or XHTML (in any version)
- HTML 4.01 Transitional doesn't allow for an XHTML xmlns attribute, nor
does it permit "short tags"
- The only "valid" short tag that you mentioned is <br />. <div/> and
<p/> are not
- Using a short tag without a space between the name and the / is also
not recommended as it causes problems for older browsers and poorly
written HTML parsers.
You appear to have made a flawed statement based upon a flawed study (no
HTML e-mail will ever be just a <head></head> combination)
