This is the complete example, the XML decleration shows up in the
output:
> foo1.xsl:
> <?xml version="1.0"?>
> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
> version="1.0">
> <xsl:template match="doc">
> <out><xsl:value-of select="."/></out>
> </xsl:template>
> </xsl:stylesheet>
>
> foo2.xsl:
> <?xml version="1.0"?>
> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
> version="1.0">
> <xsl:template match="out">
> <out><xsl:value-of select="."/> ...good to see you again!</out>
