I am surprised that epubcheck did not flag it with at least a warning if not an error.
Running Sigil's Mend will fix any missing xml header and fix any missing doctype automatically based on the epub version.

I have Just found this out.
I Installed the latest version of Sigil this morning. Very nice.
I did some work on a book in Calibre Editor and ran ePubcheck. I got no errors.
When I opened athebook to process it in Sigil I got the message about the not not being well formed. I said no to "fix the problem" and found I got the "not well formed" message when I tried to delete unused CSS and another feature . I ran epubcheck in Sigil - again no errors.
After a bit of invetigation I found that Sigil fixed the problem by adding a Doctype.
I logged onto Mobile Read and found this discussion.
Not a real problem and easily sorted but it is nice to know I got it right for once
