+// jquery.xmlns.js: xml-namespace selector support for jQuery
+//
+// This plugin modifies the jQuery tag and attribute selectors to
+// support optional namespace specifiers as defined in CSS 3:
+//
+// $("elem") - matches 'elem' nodes in the default namespace
+// $("|elem") - matches 'elem' nodes that don't have a namespace
+// $("NS|elem") - matches 'elem' nodes in declared namespace 'NS'
+// $("*|elem") - matches 'elem' nodes in any namespace
+// $("NS|*") - matches any nodes in declared namespace 'NS'
+//
+// A similar synax is also supported for attribute selectors, but note
+// that the default namespace does *not* apply to attributes - a missing
+// or empty namespace selector selects only attributes with no namespace.
+//
+// In a slight break from the W3C standards, and with a nod to ease of
+// implementation, the empty namespace URI is treated as equivalent to
+// an unspecified namespace. Plenty of browsers seem to make the same
+// assumption...
+//
+// Namespace declarations live in the $.xmlns object, which is a simple
+// mapping from namespace ids to namespace URIs. The default namespace
+// is determined by the value associated with the empty string.
+//
+// $.xmlns.D = "DAV:"
+// $.xmlns.FOO = "http://www.foo.com/xmlns/foobar"
+// $.xmlns[""] = "http://www.example.com/new/default/namespace/"
+//
+// Unfortunately this is a global setting - I can't find a way to do
+// query-object-specific namespaces since the jQuery selector machinery
+// is stateless. However, you can use the 'xmlns' function to push and
+// pop namespace delcarations with ease:
+//
+// $().xmlns({D:"DAV:"}) // pushes the DAV: namespace
+// $().xmlns("DAV:") // makes DAV: the default namespace
+// $().xmlns(false) // pops the namespace we just pushed
+// $().xmlns(false) // pops again, returning to defaults
+//
+// To execute this as a kind of "transaction", pass a function as the
+// second argument. It will be executed in the context of the current
+// jQuery object:
+//
+// $().xmlns("DAV:",function() {
+// // The default namespace is DAV: within this function,
+// // but it is reset to the previous value on exit.
+// return this.find("response").each(...);
+// }).find("div")
+//
+// If you pass a string as a function, it will be executed against the
+// current jQuery object using find(); i.e. the following will find all
+// "href" elements in the "DAV:" namespace:
+//
+// $().xmlns("DAV:","href")
+//
+//
