A namespace refers to a collection of names, or XML elements, bound to a
given name.  A very basic example is XSLT itself: its elements (stylesheet,
template, variable, etc.) are bound to the 'xsl' namespace.  In order for
the XML parser to recognize that a set of elements belong to a namespace, an
XML namespace declaration must be used:

<xsl:stylesheet xmlns:xsl="";

The value of xmlns:xx must be a globally unique Uniform Resource Identifier
(URI); this is often a URL, but can be any unique string.  (In the case of
XSLT, it should always be the above-referenced URL.)  Any elements belonging
to a declared namespace must be prefixed by the namespace name, so that
<xsl:stylesheet> has special meaning to an XSLT processor, but <stylesheet>
(note no prefix) does not.

This also allows you to use your own namespaces in an XML document, as long
as the URI you use is unique:

<xsl:stylesheet xmlns:xsl="";

There is a lot more information (surely better explained than what I've
written) in the XSLT FAQ at
