Nick-picking point: You can have an SGML document that has more than
top-level tag, because it could have elements that were inferred from the
DTD. The following is valid HTML4.0, though not XML1.0 or earlier:

<title>some title</title>
<p>some content

In such a case the html, head and body elements, and the end of the p
element were deduced. They were in the document-model, but not in the actual
file. In practice this tended to not work very well and was confusing.

There are two types of "if it works". There's the type were one says
"Because of bugs in other implementations I am forced to do something
non-standard", and there's the type were one says "I'll get paid whether I
do my job right or not." Of course the main reason that some people adopt
the first is to interoperate with stuff developed by people who have adopted
the second :(
