it is a real URL it is just that a URL may refer to any kind of
resource, not just a web page. Note though that is the _wrong_ URL.
As mentioned in the earlier replies, the URL (URI) for the XSLT namespace is
http://www.w3.org/1999/XSL/Transform

the one you gave is for an entirely different Microsoft-specific
language which is not the subject of this list.

they could, but they don't as using http URI with a domain name that you
control is the easiest way to allocate yourself a globally unique
identifier.

that's an XMl question not an XSL one, an XML declaration is never
required by the XMl parser if the file is in UTF-8 or UTF-16 encoding
(but adding one does no harm) and it is always required if the file is
not in one of those encodings.
