Standard excerpt:
The xsl:namespace-alias element declares that the namespace URI bound to the prefix specified by the stylesheet-prefix attribute
is an alias for the namespace URI bound to the prefix specified by the result-prefix attribute. Thus, the stylesheet-prefix
attribute specifies the namespace URI that will appear in the stylesheet, and the result-prefix attribute specifies the corresponding
namespace URI that will appear in the result tree.
