you could use the following stylesheet (with explanation in comments)
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/">
<Feature>
<!-- loop through each Property element -->
<xsl:for-each select="Feature/Property">
<!-- element's name is the value of child node Name -->
<xsl:element name="{Name}">
<!-- the value is the content of the child Value-->
<xsl:value-of select="Value"/>
</xsl:element>
</xsl:for-each>
</Feature>
</xsl:template>
</xsl:stylesheet>
