See

http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113/glossary.html#dt-qu
alifiedname>:
"A qualified name is the name of an element or attribute defined as the
concatenation of a local name (as defined in this specification),
optionally
preceded by a namespace prefix and colon character. See Qualified Names in
Namespaces in XML [Namespaces]."

The DOM allows you to create elements with or without prefixes.
Serialization of DOM isn't really specified (in DOM Level 2). Im DOM level
3, I'd expect it to actually respect the prefixes you assign as long it
doesn't conflict with creating a wellformed serialization.

No. You are creating an element in the namespace named
"http://xml.myurl.com/foo" and a qualified name "elem" (which happens not
to
be prefixed).
