Unfortunately jQuery selectors are not supported on Document
Fragments. Fragments are quite feature-poor and don't even provide
basic DOM-querying functionality in some browsers. For example the
following will return undefined in Firefox 3:
javascript:alert(document.createDocumentFragment().getElementsByTagName)
Browsers are starting to get better support by implementing the
Selectors API (querySelectorAll, etc.) on fragments - but it'll be a
while before widespread adoption occurs.
