XSLT is a language, which can transform an XML input (with XSLT 2.0,
we can take a Text input as well) to various kinds of outputs (like
XML, HTML and Text).

XPath is a language to address parts of the XML document. In XPath, we
write expressions, which return a set of nodes (called sequences in
XPath 2.0). Though XPath can be used standalone, but it is usually
used in combination with a language like XSLT or XQuery. XSLT and
XQuery *need* XPath.

An XSLT program file is an XML file. By using this namespace in a XSLT
file, we can distinguish between XSLT language instructions and
non-XSLT elements/attributes.
