using XSLT 2.0 there is the value #all for the attribute

namespaces is not a default behavior.
With XML ou can use qualified names not only as names for nodes but also in
element or attribute values, for instance if you want to construct an XSD
schema with XSLT, and in that case if you want for instance to have
<xs:element ref="pf1:foo"/>
in your result then, even if the prefix 'pf1' is not used in element or
attribute names, you want to preserve its declaration.
With hindsight, though, I’m sure we could have designed it better: excluding
namespaces that aren’t used in element or attribute names should probably have
been the default.
