You're creating the element with:

   <xsl:element name="policy"

The XSLT 1.0 specification says:

"XSLT processors may make use of the prefix of the QName specified in the
name attribute when selecting the prefix used for outputting the created
element as XML; however, they are not required to do so."

It looks as if you're out of luck: you've chosen an XSLT processor that (at
least in this situation) ignores the [absence of a] prefix in the name

Many XSLT 1.0 processors do make use of the prefix (or its absence), and
XSLT 2.0 mandates that they should do so unless there's a conflict with
another use of the same prefix:

"The prefix of the lexical QName specified in the name attribute (or the
absence of a prefix) is copied to the prefix part of the expanded-QName
representing the name of the new element node. In the event of a conflict
this prefix (or absence of a prefix) may subsequently be changed during the
namespace fixup process (see 5.7.3 Namespace Fixup)."
