XSLT - add prefix for namespace - xslt

Question

Here's my input XML:
<?xml version="1.0" encoding="UTF-8"?>
<Sync
xmlns="http://schema.infor.com/InforOAGIS/2" languageCode="en-US" versionID="2.8.0">
<Data>
<ID>0001</ID>
<Text>ABCD</Text>
</Data>
</Sync>
And here's my expected outcome:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Sync xmlns:ns0="http://schema.infor.com/InforOAGIS/2"
languageCode="en-US"
versionID="2.8.0">
<DataArea xmlns:dns="http://schema.infor.com/InforOAGIS/2" xmlns="">
<ID>0001</ID>
<Text>ABCD</Text>
</DataArea>
</ns0:Sync>
My current XSLT as below (https://xsltfiddle.liberty-development.net/nbiE19N).
There are 2 problems:
I have the extra xmlns="" in DataArea element. I only want to add the dns namespace.
I cannot add the ns0 prefix for my namespace
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/*:Sync">
<xsl:copy>
<xsl:copy-of select="#*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="/*:Sync/*:Data">
<DataArea>
<xsl:namespace name="dns" select="'http://schema.infor.com/InforOAGIS/2'"/>
<ID>
<xsl:value-of select="/*:Sync/*:Data/*:ID"/>
</ID>
<Text>
<xsl:value-of select="/*:Sync/*:Data/*:Text"/>
</Text>
</DataArea>
</xsl:template>
</xsl:stylesheet>
Any suggestion is appreciated!

Does this return the expected result:
XSLT 2.0
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xpath-default-namespace="http://schema.infor.com/InforOAGIS/2">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/Sync">
<ns0:Sync xmlns:ns0="http://schema.infor.com/InforOAGIS/2">
<xsl:copy-of select="#*"/>
<xsl:apply-templates/>
</ns0:Sync>
</xsl:template>
<xsl:template match="Data">
<DataArea xmlns:dns="http://schema.infor.com/InforOAGIS/2">
<xsl:apply-templates/>
</DataArea>
</xsl:template>
<xsl:template match="*">
<xsl:element name="{local-name()}">
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
P.S. I am not sure why you need the xmlns:dns="http://schema.infor.com/InforOAGIS/2" declaration; it's not being used anywhere.
