Embed pdf / excel / word files in a RTF template

Hello, I am able to embed images (that are blobs) in a report using an RTF template with:

<fo:instream-foreign-object content-type="image/jpg"> 

<xsl:value-of select="//ATTACHMENT_DATA" />

</fo:instream-foreign-object>  

however, I want to embed PDF, WORD and EXCEL documents also. I tried following:  

<fo:instream-foreign-object content-type="application/pdf">

<xsl:value-of select="//ATTACHMENT_DATA" />

</fo:instream-foreign-object>  

Does not appear to work. Is there a way to embed these file types into a report?
