XSL-FO code for external file link

[Arvind Gopal <ar...@yahoo.com.INVALID>]

Hi,
What is the XSL-FO code for creating external file link in PDF?
I am using the following for external files
<fo:basic-link color="blue" text-decoration="underline" show-destination="new">
<xsl:attribute name="external-destination"><xsl:value-of select="$leaf/@xlink:href"/></xsl:attribute>
<xsl:value-of select="$leaf/@xlink:href"/>
</fo:basic-link>
but this code is creating web link in PDF (icon is Pointing Hand with W inside it).
I want to know the code by which FOP will create file links (icon is Pointing Hand without any letter inside it).
Regards,
