The information sets of the above two instances are the same ... there is
*no* transformation going on above. Prefixes are irrelevant to XML
processing.
Note, however, that processors are *not* obliged to preserve any prefix
you
put in a QName in an xsl:element instruction ... though most do and an
example below using Saxon does. Ref. Section 7.1.2: "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."
So, you are asking for something that isn't guaranteed in XSLT for a
reason
that isn't necessary to XML giving a result that isn't different from the
original... but a candidate answer is below since you asked.
I hope this helps.
