Sorry, I referred only to Yehuda's first example for simplicity.
Please read the rest of Yehuda's first post, as his later examples
both (a) break (or at least become unnecessarily difficult) if
contextual wrappers are automatically added, and (b) don't have a
context element to apply at the time the DOM is being constructed.

If one is adding nodes into a div, one would *not* write:

var frag = parse("<tr><td>foo</tr>")
div.appendFragment(frag);

...because that would be nonsensical.  In particular, jQuery does
*not* do anything special when they see this sort of pattern - they go
to some effort to ensure that the fragment contains only the <tr> and
descendants, and then would directly insert it into the DOM as a child
of the <div>.
